Just curious, is she by herself or with any other birds? I have been experienceing this myself of late, and am at a loss as to what is causing it. They cannot pull them out themselves.... strange...
It's very strange! She is by herself with only her newly hatched chicks. I'm at a loss too :/
Hens go broody when you don’t want them to… and won’t go broody when you do.
