I noticed the other day that one of the birds has messy poo on her vent and surrounding feathers. I've also noticed a few brownish, runny poos here and there.
What could be the problem and how can I fix it?
one thing you need to do if it's sticking to the vent and feathers it should be washed off. A warm water bath or scott towels soaked in warm water. Just make sure they don't get chilled. A hair dryer would dry them quickly.
