I just got two little 2 weeks old-ish chicks like a week ago. I got what I think is a Silkie x. He seemed sleepy for a few days but then began passing dark colored, foul smelling poo, like kind of dark reddish brown and nothing solid. I watched him for a few days and he got better. Or his poo would look normal and solid and not stink most of the time. So then I got a second blue laced red wyandotte young chick. Her passings seemed fine, then they occasionally would be dark, runny and stink. Then his would periodically be foul again. They seem to both be doing better- they are alert, eating and drinking but sometimes really sleepy. And having less gross poo. I don't know what is normal chick behavior and could this possibly be cocci of which so many people talk about in chicks? I change their bedding everyday and they are living in a box right now in my house. They seem normal but maybe something a little off?
