We had a hen go broody when we don't have a rooster to fertilize the egg, so we went and got 4 fertilized eggs and put them under her, and we go out there everyday and check on her and with 8 days to go we found a baby chick popping out from under her mother, but the mother is still sitting on her eggs, Thank gosh but sometimes the mother sits outside the box and we have to put her and the chick back on the other eggs.
