But I always clean the coop each month, let them free range and give them lots of NOT rotten or moldy leftovers.Chickens can act legthargic for lots of things. For example, when they have lots of worms infested in them...
IT will actually kill chickens. I do it twice a year. Its definitely important, as it can cause them to have an infestation...thats when worms show up in their poop, or I have heard another symptom may be poop on eggs...
