This is our first time raising baby chicks and I didn't know the vent was where the chicks stooled as well . . . so I think I accidentally picked off some umbilical scabs on the poor little gals. . There's a little blood but no active bleeding now. I put some hydrogen peroxide on one of them and plan to look at them again when they de-stress a little - they were very stressed after shipping. Any wise words? Thanks!
