I have a 2 1/2 week old buttercup chick who is as small as the newborn chicks I got today. She seems to have labored breathing, slitty eyes, wants to sleep often, not very active anymore... She seems to eat rarely and drink every now and then. I have offered sugar water but doesn't seem to want it. I can't post pictures because I am new to BYC, but am very worried. My daughter is very attached. What do I do? Do I need to quarantine her tonight? She is currently sitting in my lap and her whole body is pulsing... I assume the labored breathing. Her chirp seems normal, but I have noticed she opens her beak randomly for what seems like no reason at all. Is there anything I should be doing????? I have looked up so many diseases that I have thoroughly confused myself and the symptoms don't match any 100%. Could this be pullorum? if so, do i need to kill the whole flock? I have 17 chicks all ranging newborn to 2 1/2 weeks and she is the only one acting different. They were all bought at the local feed store (in Eastern Washington). Please help. I am worried sick and have never done this before. Thank You!
