Sigh. We finally culled my Atilla. She and another pullet went broody at about ten months and she never stopped. We gave them two eggs each and they each hatched one and co-parented them (both chicks were cockerels). She and the other hen went broody again immediately afterward and at three weeks we gave them 21 day-old chicks. Atilla was firecely parenting this time, the other less so. And I do mean FIERCE. When the chicks were weaned, Atilla immediately went broody again. She's been broody now non-stop for about six months. There's no stopping her. She was losing weight without taking a break to rebuild her fat stores. Her legs were getting so stiff she was having trouble walking. When I'd take her off the nest to make her eat, drink, poop and dustbathe, she'd attack the other chickens. She was just grumpy and miserable and making everybody else miserable too. I decided to put her down because it seemed obvious to me her hormones were out of control and she was suffering.
