A broody is a hen who decides to sit on something (doesn't necessarily need to be eggs- some types of birds will try to hatch a golf ball!) and try to hatch it out. typically it takes 21 days for eggs to hatch, but sometimes a hen will sit for far longer. She wont like people touching her, and may become rather mean if you try to.
hahahahahaha that is hilarious!!!! ok so I got it..that explains why when I was a kid I always thought my grandmothers hens were evil!!! they used to chase me right out of the coop without a single egg!!!!
What does it mean if they a description of a breed says they have a single broodiness? Does that mean they only go through it 1 time? My orpington became broody, but she never got mean. We would just lift one side of her and look for an egg. She stopped now though.
