My 4 little ones are doing great so far. Pasty butt seems to have subsided a couple days ago, and their little wing feathers are already almost in inch long! They're flapping around the brooder box, digging in the dirt, etc. I gave them a tiny bit of worms today I found while pulling weeds. They weren't sure what to make of that. I think they had a good day. I still can't tell three of them apart. "Scabby Navel" is a bit fatter than the others. She still has a scabby navel, but she seems fine. Although I do think she's at the bottom of the pecking order.
