So I posted earlier about my 5 wk old chick being lethargic and seeming to have a hard time breathing but then she seemed to get better but today she has taken a turn for the worst she is making a clicking noise on top of her other symptoms and looks sick and isn't eating and drinking. I can't watch her suffer. Should I put her down what should I do. I have 9 other chicks 2 roosters and two turkeys same age please help me can't stop crying I know they are for food and its stupid but I can't help it. What do I do and how do I keep everyone else from getting sick?
