We got chicks today from the feed store, we picked them out ourselves and they looked pretty good. When we put them in the brooder we noticed one standing on one leg with the other pulled up. It keeps picking at the foot, then raising it again. It does look a little red. I've never had chicks before, only older pullets. Is this a sign of a bigger problem like an illness, or just an injury? Do chicks get bumblefoot? Should I put some coconut oil on the foot, or something else to help? Thanks!
