Quote: What most people do is feed a "flock raiser" for mixed flocks. Pullets that are very near to laying can handle layer feed, but chicks and very young birds can not tolerate the calcium levels in the layer feed. Too much calcium on young birds can destroy the liver. Especially the males. Roosters in their older years will have troubles due to all the excess calcium over the years.
Feed a flock raiser feed and keep oyster shell on the side next to the feed so the hens that are laying can get enough calcium. Always keep the calcium close to the feed. The hens will not go looking for it, but will eat more of it if it is in their faces near the feed.![]()
