I have read many posts regarding supplementing chickens with all sorts of food. My chickens have Layena pellets availble at all times as well as fresh water and oyster shells. I as well will give them a bowl of scratch every day. As I have leftovers I give it to them but this only happens a couple of times a week. After reading sooo many posts I feel like they require more. They are happy and healthy............except they do pick at two chickens BAD and my 2 roosters crow ALL day long. I have read a lot about inadequate protein. I am a little overwhelmed as to how much the chickens have cost me so I am looking at a cheaper supplement. What about cat food? Do I even need anything?
