One of my new babies (hatched 10-30) started getting pasty butt. Well I washed off her little bottom (sitz bath in a tiny bowl) and then put evoo on it (I'll pick up vaseline later but had evoo on hand) I thought nothing of it and put the baby back with it's sibblings. They started pecking at it's bottom I quickly took it out and am snuggling with it to keep it warm. But my question is....how to keep other chicks from pecking? Or will this one have to stay seperated? Theres a wet spot the size of a quarter on its bottom...when it dries more would it be okay? Any suggestions would be very appreciated!
