I keep reading that people are putting seven on there chickens. we eat our eggs and my children play with our chickens. i wont even use the stuff in my garden. there has got to be something out there that works that is not poisin. i use DE and now only a few of my barred rocks are effected. i see white clumps all around their vents and they are loosing so many feathers. i have 29 hens and only getting 6-9 eggs a day, unusal for my girls. i am cleaning the coop again tommorrow, what can i put in there before fresh shavings go down? what can i put on the hens? they have a dust bath with peat moss, wood stove ash, and DE mixed together; changed often. what am i not doing/what am i doing wrong?
