One more question if you don't mind. Do you feed all your hens starter feed in the coop when you have little ones in with them. I have read layer feed has to much calcium and will damage their kidneys.
Not a problem, I just love doing chicks this way. I am not sure if it is because I have done chicks with a broody mother for many years, and all of my hens have been raised like this, but I just watched these chicks running out and about, under layers getting a drink, right next to a feeding layer, that one got a small peck, but no big one, just a mind your manners. They are just starting to get their wing feathers.
I believe they are stronger as they are moving all over a much larger space, rougher terrain than if I had them in a brooder box with a heat lamp.
I am glad it is working out for you too.
