I searched the forums but couldn't the answer I was looking for. My husband's friend brought over some alfalfa rabbit pellets and some loose alfalfa in a bag that his rabbits wouldn't eat. He thought maybe may chickens would eat it. I figure the pellets would be alright to peck at but wasn't sure about the loose stuff. Will it cause a packed crop? Most of it looks to be around 5-6" long. My girls don't free range. They will get grass clippings occasionally.
