Messy vent please help

[BellaBokBok]

My girls both seem to have messy vents, or just poop on their butt feathers
It's just a white substance stuck to one of my girls, and the other is just a tiny bit brown
Nothing major
But the one with the white substance also has a pale comb
They're both healthy, scratching around, not lost any weight as far as I can tell
They're molting so there's no eggs
Is this something I should worry about?

Pale combs are common during a molt when everything shuts down to regrow feathers. Trim the poopy feathers off, wash there bottoms if they need it, and put some apple cider vinegar in their water and offer a bit of plain yogurt once or twice a week. Consider worming them .
