What I learned, Or what I thought I understood!

[eggsited chickens]

I was reading a book last night, and it said that the hen is the deciding factor of her offspring. A roo will automatically give off his chromosome, and if the hen doesn't give off one of hers, then the resulting chick will be a pullet. If the hen does give off a chromosome, the chick will be a cockeral. Very interesting I thought. This is why the Roos coloring and traits are passed onto the pullets.

Now I"m excited...I have a EE mating with most of my hens. If they are born with green legs, they will be pullets! I also have a speckled Sussex, and so if the pullets look like him when he was little, they are pullets! Lets hope for the best

Hi! The hen always gives a sex chromosome to the egg. The question is just which one. In birds, the hen is the one with two different sex chromosomes - she has a Z and a W, while the cock has two Z chromosomes, So, if she gives the Z, the chick is a cockeral. If she gives the W, the chick will be a pullet.

This is the actual saying in the book "Every fertilized egg contains a sex chromosome from the cock, but a hen transmits her sex chromosome to only 50% of the eggs she lays. IF a fertilized egg contains chromosomes from both the cock and hen, it will hatch into a cockerel; if it contains only the single chromosome contributed by the cock, it will hatch into a pullet.

Since each egg has a 50/50 chance of containing two chromosomes, eggs hatch in approximately a 50/50 ratio of cockerels to pullets."

found in Storey's Guide to Raising Chickens page 78

Green legs are not on Sex Chromosome.I have EE hen who pass her green legs to all sons and doughters.Barring,Gold-Silver genes are on Z Sex chromosome and are used to produse Sex Links.

So then what the book is saying is not true?

LOL I have Storey's Guide to Raising Chickens and on page 78 it is talking about how to raise meat chickens. Maybe there are different versions?

Rooster has 2 Z chromosomes Hen has 1 Z and 1 W. If egg take one Z from the father and one Z from the mother chick will be boy.If egg take one Z from father and one W from mother-the chick will be girl.Because hen has only 2 sex chromosomes-one Z and one W are 50/50% chance for each sex.Will be Z or W-boy or girl.Only Z cromosome cary some color genes(barring,Gold-Silver and some other) but no all of them.There are more then 40 other chromosomes who cary many color genes ( black color,white,columbian pattern,motled and etc).I am done,it was too much English for me.Sorry for wrong sp.I think you are on right way- reading books

So, what you guys are saying is it is the opposite of us humans with the X and Y, that the XX = girl and the XY - boy. But with chickens the ZZ = boy and ZW = girl. Correct?

Yes
