I wouldn't know how to tell if I have a broody either. I wish I had one 2 weeks ago when I set eggs though. That incubator is just pulling power when I could be using chicken power.good boy Jasp!
This was my black orp Lila. It literally took this hen over 2 mo to get her babies. She had only been my second broody so it took me a week or so to realize that's what she wanted. (I've gotten better now, thank goodness ) I kept putting eggs under her I though would be black or lav and she would sit for a few days and then completely change nests.so finally, I had to go out every two hours or so and make sure she was sitting on the right one and move her if she wasn't. For 3 weeks. Everyday. I dont know who was happier, her or me.
.. so the eggs went back to the bator.... a half hour later the power went out. only for an hour 
. I gave her one egg she had and she didn't attack , pulled it in under her. She will get another chance later.
I have a couple chickens, from the brooder days, that jump up on me and are tame. But the last couple of years they are all raised by a broody hen. 
The chickens were allowed into the garden to scavenge while I was working out there. They took full advantage of the freshly turned compost to find bugs and yummy (to the chickens at least) bits. The scratched all over the ground were my compost wad previously and also got on top of the 3ft pile after I moved or compost heap to the new bin. They were testing my patience as they kept getting in the way while I was using a pitchfork to turn and move the compost.
