There is no question in my mind...she is broody. Our buff orpington would hiss, growl. Brussel up like a turkey. The blue Wyandotte didn't make a sound. This has worked for us and goes against all the advice given...at every opportunity I have taken them out of the nesting box and at first put them on the ground then after the second day it was unceremoniously dumped out and run them out into the run. The orpington took a full week of that while the wynndotte was over it in 3 days. The orpington had been in "chicken jail 3 time prior to this last episode. She would last about 6 weeks and back to broody, this time with no jail time she has been great for 8-9 weeks and even laying eggs. It may not work for you but you can try it and see ...there's always jail time.
