I have some chick that aren't quite 2 weeks old yet. I was just down to see them after work. They are all active and look fine, but some have a lot of poop built up on their rears. They are very skittish, but I managed to get hold of one of the worst. The vent is clear, but the poop is stuck to the skin quite firmly. It could be a chore to get them all cleaned up. My questions are: As long is the vent is clear, is it harmful? and Will their feathers push it off when they come in? Thanks.
