what do broody hens look like? what do they sound like ? and how long do they sit on the eggs
They cluck, growl when disturbed,and walk around ruffed up with wings down. The number of eggs they will brood can be anywhere from 0 (they will brood an empty nest) to 12+ eggs. When a hen stick to a nest day and night she is broody.
Does she have a nest with eggs? If she is going broody it could be soon. Some of my hens have gone broody with no warning what-so-ever. Others have walked around, puffed up and growling?clucking for days before they settled down. One never did settle down to brooding full time.
I leave eggs as they are laid or replace them with dummies when I want a broody. If you know which nest box she uses consider leaving a few eggs in it. Dummy eggs if it is a communal nest. Lea Presenting a hen with a nest of eggs WILL NOT make a hen go broody, but it does provide inducement.
