We got a shipment of baby chicks at 6:30 this morning, most of them for my mom, who came and picked them up a couple hours later. They all seemed to be doing fine when they were here, but now one of them has what my mom is calling a crusty bump on its belly, and is very listless. Just laying around - they took it out of the brooder because the others were pecking it as it laid on the floor. The attached is a photo of the bump - hard to tell what it really looks like, but you can see how it's just laying in my sister's hands. I'm trying to see if they can take a better photo. If I get a better one, I'll upload it, but wanted to try to get some advice as quickly as possible. Anyone have any ideas what they can do for it?
