Hello I just recently got new Chicks they are about 2 weeks old now and one of them has a very poopy butt. As I was looking at her I she tried to poop but instead her vent just swelled up to the size a little bit more than a pea and could barely get the poop out. I don't know what to do so I cleaned her with some warm water. Please help. Here are some pictures of bumble bee.
