I got four chicks a week ago and all of them are doing great except For one it has a bump on its vent that is red and swollen. I have been cleaning it’s butt and applying Vaseline daily but it doesn’t look like it’s getting any better. It looks like it has something white oozing out of its vent. It’s starting to lose its feathers around it’s butt and I don’t know if it matters but it still has its umbilical cord scab and it has a one crooked toe. It is eating, drinking and chirping I’ve never had anything like this happen before I’m really worried.
