I picked one of the babies up earlier to hold it for a minute and such and i noticed that the bottom of it's feet were all cracked. I checked the others and same thing, some worse than others. I've never had this problem before. They're brooded on straw & sometimes pellets. I put some Stall Dry in the other day because of flies though, could the Stall dry be causing the cracked feet? is there anythign I should do for them? They're not open sores or anything, just very cracked on some.
