I’m trying to intergrade my four ISA brown chicks with my two production white year old hens. They’re getting along pretty well, but my hens are eating laying pellets and my chicks are on crumbles. Well my hens want to eat the chicks feed and my chicks go after the pellets. I’ve got the feeders in different areas. Is it ok for them to be eating each other’s feed? Thank you in advance for helping this new chicken Momma.
