I would not count a hen as broody until she has been consistently on the nest for at least three days and nights in a row. Most hens will not go broody or hatch on the late fall to winter, but they don't always follow the "rules". Every bird is different. Roosters will breed hens of different breeds. Many roosters start breeding around 4-6 months old. I don't know if they will consistently fertilize every egg at that stage or not.I had a hen stay out of the coop last night... I suspect possibly on top of hay stack ? And then showed up this am... Would this be broody behavior ? Also I have bantums and Americannas hens was hust given 2silky roos that look to be teen agers...
At what age can roos breed ? And will they breed hens not of there breed ?
