Well... I have minimal experience... but from what I've read, true "broodiness" is a much more dedicated and hyper-focused behavior... some hens even get violent, in an effort to protect the nest. My girl isn't displaying violence, but she does bristle her head and neck feathers and "growl" at me when I come out. But then she does allow me to pick her up and collect eggs. She eats and scratches for less than five minutes before heading back in. Another "sign" I can definitely attest to, comes from the fact that a broody hen isn't getting up to eliminate for hours at a time... the results are... big. stinky. poos.Mine is only staying on the nest for a couple hours a day but I put an egg in front of her and she did tuck it under. What do you recommend?
