Ok we have a first time mama hen. 8 month old Swedish flower. We got our first chick Wednesday. I came home today to check and she was out with the little one plus another! Unfortunately the newer one was on the cement slab near the food and eyes closed. It was so cold. Peeping. So I scooped it up waiting for mama to get back on the nest (there's two more eggs unhatched). She didn't go so I put it in a brooder with a heat lamp. I just checked on it (an hour later) and it's bright eyed and peeping. Moving around a bit. When can or should I put it under the mama again?
