I supply my chicks with starter feed, however, when they go out it the run, they have access to the layer feed that is for my laying hens. I just read that layer feed is bad for chicks. I got the chicks when they were 2 weeks old, and they are now 3 1/2 weeks old. Have I damaged them now? And can you give any suggestions on how I can keep them from the laying hens feed? All free range. I have a huge automatic feeder for the hens and rooster. I have separate feeding troughs for the chicks that I keep inside the coop. I am moving one of them outside. I was thinking of raising the hens feeder up higher, so the chicks will have difficulty getting to the feed. Does anyone have any other suggestions?
