Now here's a strange thing.Actually, Ribh do your broody hens take a few weeks off between sitting? What I really want to know is how frequently hens go on the brood, or is each hen different? Ivy and Mary have brooded twice this summer, Peggy once.
The marans hens were not broody self sufficient. Even Ruffles as a second generation hen needed taking off her nest for the fist few days. She got the hang of it quite quickly but the original Marans were all likely to lose condition.
The original bantams which were not pure breeds (?) got off the nests every day and some would spend easily an hour, weather dependent, on eating bathing and letting the rest of their tribe know they were broody.
The mixes, Marans and Bantams are also broody self sufficient.
The next generations all get off their nests and maintain body condition to the point that some put on weight while sitting.
