My bantam sat on two eggs and once hatched she tried to get rid of the chicks. Found one dead on floor and second one alive on floor later. Put it back with her and watched as she tried to shove it out and over the ledge. Saved it and it's survived 4 days and Seems healthy. Should I buy one or two more chicks to keep it company? Worried about introducing it later to hens all by itself. Any ideas?
