The chicks I got from @Lapeerian
two weeks ago are doing great. They have been in with the hens for a week with no issues- the two groups mostly stay apart, but they are used to each other now. These girls have been growing like mad! Still terrified of me.

One thing I just noticed this morning and wondered about is that one of them, in the middle here, has whitish-pink legs, while the other two have yellow legs. They are mixed, I think Wyandotte and EE? Does the leg color have to do with mixed parentage?
