My Hen (cartridge Cochin) was broody for 3 weeks, her eggs were rotten. I ordered her 5 1 day old chicks, put them under her and took the eggs away. She did great with them, they were born May 31st. They were penned off in the coop until they snuck through the fencing a week ago and she flew over. They have all been living in the coop with 5 other hens and a rooster and the outside run just fine. This morning the mother hen had been mauled and one other hen was dead but intact. All's that I thought were left of the babies were feet. But then I realized later in the day 2 of the babies had escaped the run and were in some bushes around the house. If I put them back in the coop without the mother will the other hens bully them, even though they hadn't previously? All of the original 7 were raised in a broader with a heat lamp. I could do that if I have to, but these chicks seem a lot hardier and love to play in the run!
