Yes!! It’s about 10 before she goes broody! Did you break her or just let her go? I tried to let her go the first time but she was like that for over 21 days so I broke her instead.
how old is she?
I never broke her - I don't see the point when they are really broody and will be back to brooding before you know it. It is just a hormonal change that stimulates them to sit, and our girl would sit for up to 6 weeks, then she'd give up, do a bit of a molt, and start laying her 10 eggs before repeating the process. She did that for her first 2 summers (she was a winter baby) then the last 2 years she's just gone broody maybe once or twice each summer. She's really slowed down in the egg laying department, but she's a pretty girl so we keep her around and I'd be surprised if she goes broody at all this summer (I'm in the southern hemisphere).
Chickens don't have the same sort of attachment to their babies as we do, and she won't be sad that nothing hatches. They are a lot more philosophical about these things than we are.
