So I just wanted to add a few things. I have cleaned some of the chick's bums and some of the fuzz did come off initially. It didnt seem to matter and a few days later things were clean and clear. Just as long as you are not ripping and causing irritation or bleeding I think you are good to go. That baby fuzz will be gone soon enough naturally. I started to put Bragg's ACV into their water at age 1 week (just found out about it from another post here) and I have not had a single pasty bum in five days now. I will ALWAYS use this in their water for all ages for it has tremendous health benefits for them. I have never had a chick get constipated. I would try some of the live bacteria yogurt with a bit of oil mixed in it as well. Good luck everyone! Who knew that I would be wiping chicken butts!!! LOL
