pips&peeps :
It can't be half ameraucana, they have white skin. White skin is dominant to yellow skin and the chick would have white skin but carry the yellow skin gene.
So the ameraucana is not the sire.
Edited to add: Unless your "ameraucana" is an easter egger and carries the recessive yellow skin gene.
Do you have a picture of your ameraucanas?
HHMMM!! Ok, well this leads to questions, since I am still learning about all the genetics. I thought that leg color was a co-dominance situation since EE's end up often with green legs, yellow plus slate makes green. I also thought that yellow legs means yellow skin, is that right? I assume the yellow feet will end up green in the end. It is a possibility that my EE roo was the daddy not my pure blue. The EE roo was from eggs I purchased off of
Ebay, he was blue out of "Lavender split" stock and he had silver leakage. I had planned to keep him to breed to my mixed laying flock because of these flaws. His legs were black, but his brother's were green.... This roo was killed by a predator while protecting his hens 2 or 3 weeks or so before I set these eggs. I guess he could have been the daddy, he was my dominant roo, but the timing is stretching it.
Lavender Split at 5 weeks of age. Potential sire on left, culled brother on right.
Other potential sire is a Whitmore bred Ameraucana. I know its not a great pic, but it is the only one I have taken. It was in quarantine the day after I picked him up. He did have a nice beard, but he plucked it out due to stress when he first arrived.
Due to the time lapse, I had thought this one was the sire. I had gotten this blue roo to use for my Ameraucana flock, he came from Whitmore Farm in Maryland, so I am sure he wouldn't have contributed a yellow leg/skin genes.
I hadn't planned on hatching these chicks, I didn't plan to start breeding and hatching until Feb. I hatched these out for my daughter, to console her after losing her pet cochin. I only had 4 cochin eggs and two of those had been in my fridge. I only put this egg in to better my odds of having two live chicks. With 18 hens and pullets out there, most of which are production layers from a hatchery, it is often hard to know which hens lay which eggs. I thought I knew, I appear to have been wrong. I don't have my chickens separated into breeding pens yet. They all free range together. I know the cochin roo isn't trying to mate any of LF hens, he is to low in the pecking order, all the hens push him around.
