I have a Buff Orpington that developed exactly the came condition when she was a week old. She eats and drinks fine and gets around okay. I'm just going to let her stay as long as she doesn't seem to suffer.
I have a baby buff that has the same problem. She is two weeks old today and we noticed it. All others are just fine. She gets around and seems to eat and drink without any problem but her neck is definitely growing crooked.
