We got some chicks last week and one of them has been showing signs of cocci for 2 or 3 days. I just gave her a drop of undiluted Corid in her mouth and some Corid in the water. She's around 7 weeks old. I should have treated her when I suspected it. Why I didn't? I have no clue except for it's been cold the past few days so I thought maybe she was puffed up because she's cold like some of my older chickens do. She would "unpuff" when she was walking around so I didn't think much of it. I think she's eating and drinking (she got a little excited for grass). She gets very active when I try to pick her up and put Corid in her mouth. She's my grandfather's chick so I don't want anything to happen to her. For some reason my grandfather wanted this little girl over everyone else. Never has he wanted his own chicken... until she came along. (How sweet lol) I don't know if I'd consider this severe or mild. She tries to sleep standing up. Somewhat lethargic but not as much as my older girl who had cocci a few months ago. Right now we're dealing with cocci and a respiratory thing in my older ones. So much medication going into their water! So... do you think she'll make it out of this? She's a Faverolle / Cochin cross (Partridge Cochin, so she's beautiful). She looks like a tiny bald eagle, so we named her Eagle. Just some additional, useless information lol.
