In the January / February 2021 issue , we gave you a feature about somefabulously fowl fact . We had so many that we decided to split the feature article in one-half ! For part two , we have some more interesting tidbits , from spontaneous gender reversal to complexness of communication , about your favorite livestock favourite .
Gender Roles& Spontaneous Sex Reversal
Did you hump that occasionally poultry can be both genders ? It ’s a phenomenon called gynandromorphism .
In “ Chicken ’s Split Sex Identity Revealed , ” published in the March 2010 issue of the scientific journalNature , the research team found that about 1 in 10,000 chickens are born as intersex . Their cells are normal but one-half of their prison cell are virile and one-half are distaff .
Despite this , they commonly only have one of the sex reed organ ( bollock or ovaries ) .
Hens can also seem to change gender , in a process known as spontaneous sexual urge reversal . They are still distaff but take on some male characteristics .
A disease damage the poulet ’s bequeath ovary usually induce spontaneous sex activity turnaround . The right ovary then develops and becomes an ovotestis . The ovotestis can release androgens leading to a hen that look and acts more like a cock .
In“Sex Reversal in Chickens ” ( 2010 ) , poultry researchers Jacqueline Jacob and F. Ben Mather summarise that “ every once in a while , you hear a story about a biddy that deepen into a cock . Such news report are often conform to with skepticism , but gender reversals do , in fact , go on , although not very frequently .

“ To date , however , spontaneous sexuality reversal from male to female person has not been reported . In spontaneous sex setback , only the phenotype is alter . Genetically , the bird persist a female , but outwardly it appears manlike . ”

Chickens Dream!
scientific discipline demonstrate Gallus gallus dream , too ! Just like us , birds experience REM ( rapid centre apparent movement ) sleep , the sleep microscope stage associate with stargaze . However , their sleep phase agenda is unlike from world .
Humans cycle between SWS ( obtuse moving ridge eternal sleep ) and REM sleep quietus every 90 minutes , while birds do it every 10 to 15 minutes , according to inquiry print in 2008 inProceedings of the National Academy of Sciences , the official diary of the National Academy of Sciences .
The field ( “ Mammalian - corresponding Features of Sleep Structure in Zebra Finches ” ) put forward that birds divvy up many features of rest in usual with mammalian . But this corporate entourage of characteristics had not been cognise in any one mintage outside of mammals . Researchers hypothesize that share , ancestral characteristic of sleep evolved under selective pressures common to songbirds and mammal .

Sleep is crucial for chickens but leave them vulnerable to predators . Nature has a root .
Chickens can sleep with one oculus open and one heart closed ! It ’s a stage of sleep called “ unihemispheric slow - wave sleep ” that allows half the brain to get residuum while the other half stay alarm for predators .
Bigger & Brighter
inquiry express that hens often prefer roosters with large and brighter combs . And roosters seem to treasure big - combed hens as well .
scientist at Linköping University in Sweden found that hen with the largest cockscomb are potential to get a bigger dose of sperm from roosters , according to a paper demo in the science journalPLoS Genetics .
sizing matter regarding wattles , too . hen are often drawn to with child and bright wattle as well as frequent tidbitting behavior ( when roosters pick up food and fell it in front of them ) .
The December 2009 issue ofAnimal Behaviourincludes results of a study that used alive cock . Hens respond most quickly to those with normal or stationary wattles , rather than one lacking lappet or ones with an extra floppy wattle ( that seem smaller in sizing from flopping so much).Michael Anfang / Unsplash
ostensibly , wattles help a rooster depict attention to himself as he tidbits . It ’s like to a cat in eye - catching vesture showing off his good dance moves !
“ wattle are thin , elastic structures that hang generally from a male ’s lower jawbone and deviate in size over a male ’s lifetime , ” researcher wrote .
“ These structures sway rapidly during tidbitting , potentially increasing the surface area around the head and increasing image question . male also tidbit more vigorously with extremely preferred food , increase wattle displacement and thereby potentially affect information content . ”
Results let on that the nutrient - search responseof receivers was full-bodied to changes in wattle sizeand movement . They suggested that wattles upkeep enhance signaling efficacy .

Complex Communication
Chicken language is more complex than some gain . Scientists have found chickens have more than 30 placeable phrase they use to communicate , and their language is very nuanced .
For example , chickens give alarm call when they see predators . But the study“On the significance of Alarm call … ” in the July 1993 issue ofAnimal Behaviour , showed that when roosters observe predators , they give a entirely dissimilar alarm call depending on the case of predator ( aerial versus terrestrial ) .
Furthermore , they follow the situation first . If hen are nearby , they usually let out the consternation call . But if they are around other Male or alone , they often stay quiet . They ’re also right smart more likely to let out the alert call if there is actually somewhere like a bush nearby to enshroud .
Well , that ’s all the mythical fowl fact we have at the moment . We ’ll keep you updated on any scientific breakthroughs in the poultry world .
In the lag , initiate taking your own note . Do your chickens have communicating oddity ? Have you seen spontaneous sex reversal in your flock ?
You might disclose some interesting biological natural event in your own heap !
Sidebar: Solar-PoweredEggs
Reader Regan Rockhill from Maryland passed along a bit of neat advice :
“ I have a small hobby farm with a small wimp henhouse with no electricity to it , ” he pen us . “ I have a solar - power , reflex open / close room access for my henhouse which sour cracking , and I also buy a solar visible light with a distant mastery ( less than $ 20 ) .
“ At Nox , I move around the light on and compact the clit for it to go off in four minute . There are three level of lights , so I can select the lower brightness but keep the cage unhorse . By pressing one release , I can get four more hour of lighter for my chickens during the wintertime month .
“ It works bully and is gentle to install . just come out the little solar panel alfresco , start the wire into the coop and bind it to the bulb . It ’s a bully way to get laying hen more Light Within at next to no price . ”This article originally appear in the May / June 2021 issue ofChickensmagazine .
