Found these while cleaning the coop today. The flock is about 6 weeks old and hasn't had access to the outdoors other than what comes in on my shoes. I did a course of Corid almost 2 weeks ago when I couldn't find a reason for one chick to be slow growing and lethargic. (Didn't help; the chick died. Also that was before they moved out to the coop.) They haven't had berries or any other treats recently, but wild birds have been using that barn for years. It was swept out and enclosed with hardware cloth before the chicklets moved in, but not disinfected. Nobody seems to be acting off in any way. Should I do another course of Corid? Thoughts? Thanks!
