Texaschickmom- I will mostly agree with Mathace
Green seems to have a nice amount of white for a breeder, proper colored feet and legs, really excellent width of back, good shape and angle to the body and a more proper tail angle. There is something that I don't like about the head but not sure what it is, maybe the comb not really having a blade, but something.
White has a lot of white in the tail and too high of set to the tail, looks like one crooked toe but could be standing on something, nice width of back, good shape and angle to the body. I think white has the best comb out of all of them
Yellow has too much white throughout its body and I think the head is vary narrow, he also has a bad comb with a twist and maybe a side sprig, his body angle is up to high and he has multiple crooked toes, it is hard to tell from photos but I also think he is the most narrow in the back. He goes to the bottom of my list for keepers!
Black seems to have a better head but has a bad comb, his feet and legs look good, his body angle is ok, tail angle is way too high and he has a lot of white and too much black with no white tips in the hackles.
Will be interested to see the weights you get on them. If I were to retain one I would keep green or maybe white.
I need to post my photos of our three older hens that are hatchery stock.
Mathace and 3 Rivers I will try to remember to ask Tony what he feeds and will take photos as the chicks are growing. Remember though that they will not arrive for another 3-6 weeks.
