I'm going to be starting a backyard flock this year and will be raising 12 chicks. I also am borrowing 5 laying hens from a friend to provide us with eggs untill mine are old enough to start laying. I was wondering what feed would be best once these birds are all together (after the chicks are old enough to go to the coop). Keeping them sperate isn't a very good option for me. I've read that the layers should be eating laying ration, but that the extra calcium can be harmfull to pullets that are not yet laying. Thanks for any advice.
