I have 2 coops, one with silkies, one with large fowl. I took my friends chickens a few weeks back, I know the chickens well and I've observed them over the months and they were healthy so I didn't quarantine them. One of the silkies started with cocci after about a week. I've battled with it myself with the silkies since getting them. The same one kept getting it. Well, I figured the new silkies had to get used to different strains of the cocci because it was a different soil they were on. I treated them and separated them and they are fine. Meanwhile, one of my current silkies started acting funny. She/he was just puffing up and acting lethargic. So I thougth maybe he/she had cocci also and I started just treating them all. He/she felt really light and didn't seem to have a full crop ever. I don't know what the deal was. I thought everything was fine since they were all acting ok until I just went out to get their water to change it and he is dead. Meanwhile, in my LF coop last week one of my dominiques jumped down from the eaves and broke her leg. She's been hopping around. Everyone else is doing great. Until this morning, I just went out there and my other dominique is laying on the floor twitching like. barely moving at all. I have no idea what is going on. I've never had any issues in the 3 1/2 years that I've owned chickens. I didn't think anything was wrong with her, but now that I think back, her comb wasn't bright red, but I just choked that up to her not laying eggs right now or something. I guess she wasn't feeling good. Is there anything I should/can do? I honestly have no idea what is going on. And I haven't noticed any general symptoms either. She was acting fine, I didn't see her puffing up or anything. I really just want to cry right now. Melon was my favorite chicken. SHe was SO sweet. She was hatched in March I think. ETA: the dominique, Melon, when I locked them up last night she was roosting with the others in the eaves. I need to figure out a way to block that off, but haven't had the chance yet.
