Hmm - I so wish they wouldn't do that. Found one outdoor clutch (the dogs found it, and ate half the eggs), but no hen sitting, one hen missing. Smug fox

Our oldest hen is broody at the moment (sitting on nothing) inside the henhouse. Safe - maybe that's why she's survived so long

Now I've spotted a tunnel at the base of a stack of old hay, hen sized, well worn. No hens missing, but I think they may be laying in there for the day someone decides to sit. It's one of those places which requires contortions, standing on your head, and a torch to see inside - aha, a job for Mr F.
