This may be a dumb question, but I'll ask anyway. If I put betadine on the unabsorbed yolk sac, about the size of a pea (maybe a little smaller), will it hurt the chicken if the sac is eventually absorbed? Thanks. I've never had this happen before, so I need help. A chick hatched out late last night and it has a red "bubble" hanging from its bottom. The yolk sac didn't fully absorb. Will this eventually absorb, or is it best to go ahead and cull? Thanks.
