I have three buff orpington chicks that just turned 8 weeks old. They seem to be acting healthy but this morning in their brooder box there was two places where dropping had blood in them. Sorry, no pictures. I got these as day-old chicks from Orscheln Farm Supply. They have been stressed the last week. The original pen I had them in had the problem of my dog digging under the fence. I knew it was early, but I moved them in with my other hens (all over a year old). I didn't think there was much bullying, but the chicks were scared and hid behind the nest boxes. So now I have them in a pet carrier in the outdoor pen with the other hens, and have them segregated by a chicken wire fence I put up. They now have a little run area of their own that they are using. I got these from a big farm supply place; I thought they were treated for coccidosis but I don't know for sure. They were started on medicated starter, but have been on non-medicated starter/grower for about three weeks now. What should I be doing for them? Do I need to worry about my hens on the other side of the fence? I have some Rooster Booster wormer, should I give them some in their feed or are they too young? The package doesn't specify ages.
