Hi, I have 8 b/o pullets all around 21 weeks old. They have all pretty much started laying. One I call "Big Red" has always seemed to have a very droopy comb. I thought it was funny but lately I've noticed it turning pale at times. She seems fine otherwise. I never thought it could be a sign that something is wrong but I started reading other posts and it's sometimes listed as a symptom. I feel bad laughing at her now and I am completely worried that there might be something else going on. She's a wonderfully nice bird with a great personality - very sweet!
