Baby chick food will make your laying hens fat and egg production will drop, they will also eat a lot more as they like it, that will cost you good money, layers pellets is not good for chicks. if you can get a plastic container put the chicks feeder inside and make a hole just enough for the chicks to get in, it will be difficult to train them to use it as they listen to their mother who has no access to the feeder but yo can try anyway
