If you sneak the chick under the hen at night, stay there for a while to make sure the hen does not reject it. I tried it once but my hen did not accept the chick. It was the saddest thing to watch that chick try to get back looking for safety and the mother didn't take it and tried to hurt it. I had to hand raise it which didn't work out too well either because it was a rooster. When it was mature he attacked everyone in sight and drew blood. We had to get rid of him because it became too dangerous to go in there to feed them. This is the egg I hatched on my chest. :0(
