Ok I am sure there are a hundred threads on this.. My hens are about 3 years old.. I have 14 of them, about half of them have poopy butt, pretty bad.. now that being said, it has rained here every day, and the run is a little muddy... I have looked for signs in the poop, all poops look normal.. they get Diatomaceous earth weekly, so I honestly don't think its a worm problem... I don't see any skin issues, no mites.. just poopy butt... is this normal or does it have something to do with the age of the hens?? Also I know the ladies are older, so their feathers are starting to look pretty raged...now they are laying excellent .. out of 14 hens I get 11 to 12 eggs per day... and at 3 years old.. I think that is just amazing.. Should I be worried about the poopy butt and feathers??? I feed them only a 20% layer and then they free range some but not all day.. Thanks.
