Please help. I don't know what to do. I have a feeling someone will tell me I have to cull the entire flocks, but Im not willing to go there. We have a flock of 7 hens outside, about 2 years old. One of the RLB wyandottes started sneezing, and she's been flicking her head. Last night she did a woodpecker thing against the wall when I locked their coop and there was blood all over her beak (I actually can't remember if that was this morning or a day ago). She had splattered blood all over the wall too. Anyway, she was acting fine today other than the sneezing but there had been a clicking noise too, and tonight when I went to lock their coop, I noticed a couple of pine shavings by the chicken door had blood on them (just cleaned the coop today so I know it's fresh), and when I opened the people door I noticed her mouth was full of white mucus! To make matters worse, I have 13 4 week old chicks and 5 2 week old chicks in the house. To make matters even worse again, I peaked in on the chicks this afternoon after I had been out cleaning the coop, and one of the baby babies looked like it had blood on its wing, so I reached in and grabbed her. Turns out another chick had pooped on her, so it was dried poop, but I hadn't washed my hands, and hadn't changed clothes, so now I'm even more afraid of biosecurity issues. Back to the sick one though, I have Denagard. I don't know if I should have, but I mixed some up with water and went back out and forced her to drink a few swallows of it. I don't even know if that will help, but I panicked. What do I do??? I'm freaking out just a little at this point. Please help!!!
