That sounds like Sage advice. The standing hasn't been an issue for her. I'll try letting her out tomorrow. She was even going in the nest at night. Biggest problem was that she was pecking any other chicken that would try and get into the nesting boxes.Two things:
1 - Put 1/2" hardware cloth on the bottom so she has something to stand on. You'll have to be careful there are no pokey parts.
2 - DO NOT leave her in there until she lays an egg!!!! Their egg laying hormones (or whatever) shut down when the broody hormones kick in and don't start up for some time after the broody ones have subsided. Do not expect an egg for about 5 days, maybe more, once she is no longer broody. Go by her actions. If she stops being clucky, stops being agitated, let her out in the morning and see what she does. If she goes back to her personal "regular" chicken vocalizations, doesn't flare, doesn't cluck, doesn't head back to the nest box within minutes of being released, she is probably over it. If she heads back to the nests, put her back in the buster until the next day. Since they won't lay for that ~5 day period, there is no reason for her to want to be in the nest other than still being broody.
