Pepper has been determinedly sitting on other people's eggs for a couple of weeks now. She would happily spend the whole day in the nest box. When the other eggs are laid though, I chuck her out.
She then squawks at me and sits tight on the run floor for a few minutes. Then when she realises the house door has been shut, she admits it's a fair cop and rushes to the feeders to tank up furiously on pellets and water. At this point, when I'm home, I let them out into their own (fenced) bit of the garden and she enjoys scratching and stuffing her beak in there with the others. She's such a little thing too and only laid for a few weeks before going on strike to go broody. Two of the older hens seem to have reached the Henopause so we aren't getting a whole lot of eggs just now!
