I got 3 chicks on Sunday. First time chicken owner! We were told the are sex-linked Red Stars, females are yellow, males would be brown. Two of them look yellow without doubt. What about the one in the front? He/She's a bit darker but NOT brown, but has dark wing tips. They are only 5 days old.
Here you can see the dark feathers starting to grow, only on the wings though.
And here's one more of him (?)
Thanks for all your input!
