My broody just gave up on her eggs. We were not sure when she started sitting so maybe they had gone over time, bit I did find some mites on the eggs so maybe that was the problem. She is now powdered, the house cleared, bedding burned, eggs thrown out and I am just about to frazzle the whole house with the magic weed wand again. No evidence of mites anywhere else than on the eggs, but better safe than sorry. It does mean that I can have my polytunnel to myself this winter instead of sharing it with a large brood of chicks and their mum but on the down side we won't have much stock to sell early next year. I am wondering if it might be better to hatch eggs in an incubator then pop the new chicks under a convenient broody to rear them. With Scots Greys they really do need a mother to teach them all about life as a totally free range bird, as well as to protect them from predators.
