I hatched my first lot of chicks yesterday and I am thrilled, they all look so happy and they are chirping away and eating fine. However, I noticed one of the chicks is staying under the brooder plate constantly and won't stand properly. So I've checked it out and I found that it's vent is all crusty and looks slightly prolapsed. What do I do? Can I fix this without harming the poor little thing? Thanks in advance!
