Stop the oats immediately. Make sure the crumble is for chicks and not a layer type crumble.

It is for chicks. I just double checked the bag

The temp under the heat lamp is 93 degrees. The kennel they are in is massive as it fit our 130 pound dog. So they move out from under when they are too hot. I have them on started crumble. I don't have any other chickens and as far as I know the hatchery I got them from didn't have them with any other chicks or chickens either.

What hatchery did you get them from? Did you buy the liquid or powdered Corid?
