One of our hens surprised us with 14 chicks a couple of weeks ago. They are now over 2 weeks old and most of them are doing great. We are keeping them with their mama inside the coop in a large dog kennel, with water and chick starter. The kennel bottom has sand in it. This is how we've always done chicks and it usually works well. Anyway, now that they're a bit older we let them out of the kennel to run around with the other hens. They can access the big chicken's feed but it's 16% grower so no extra calcium. Today when I was checking on them, I noticed one of the chicks is quite a bit smaller than the others and was just sitting in one spot not really moving. When I picked her up to check on her, realized she had a lot of poop around her vent. I cleaned her up and put her back with the mama, and will continue to check on her, but is there anything else I can do for her? When I put her back she was walking around a little bit, but definitely something is off about her compared to the others. Is it just a matter of her needing to poop now and then she'll likely be okay? What would cause pasty butt under a mama hen, I thought the hens were supposed to clean them up? (We've never had it happen before.) Mama hen is a very new mama, and also still very young herself (6-7 months), so maybe inexperience combined with so many chicks? Thanks!
