New chicken owner expanding the flock. I put five eggs under a broody hen and have four chicks. They are 11 days old and I believe they are a mixed, Cochin and Sussex. Is it too early to get an idea on sex? Can I use the feather growth to tell if they are not 100% Cochin? I am pretty sure the one with wings and pin feathers is a pullet and I am hoping the red one is as well. Not sure about the other two. The tiny chick (Lazarus) was stuck in the egg. I assisted after 24 hours and was sure he would die as he could not stand or walk for several days. He can now keep up with the gang, but I think he is a Roo.
