I've been feeding my chickens layer mash. I've heard that some people use pellets but have just stuck with mash. Lately I've noticed that the mash is clumping up and getting stuck in the feeder and I have to jam a stick in it to break it up. Why is this happening? I'm considering switching to pellets but don't know if the chickens will like them. Anyone ever switch from mash to pellets? Do the chickens adjust to the pellets easily? Are there any benefits of pellets? I would think they wouldn't jam up in the feeder the way the mash is, right?
