I posted here a month ago that my 3 ex-battery hens were sleeping in their nesting boxes. As suggested i have been blocking off the nest boxes in the afternoon and after dark i've been lifting them onto the perch to roost. One is uausally up but i lift the others. Everyone thinks i'm mad! Anyway, i forgot to put the board to block off the nest boxes today, i've just been out and they were all snuggled up in the nest boxes!!! Will they ever get it?! Will i have to do this forever??
