Mine did too ... with these little cuties!!!Day 7 update:
My broody Leghorn finally voluntarily came out of the nest box this morning!
Every morning in the past week, I made oatmeal + veggie + meal worm + layer feed mash, let her have some in the nest first, then remove her from the coop to finish up breakfast outside on the lawn. Then I locked her out of the coop, either in the attached run to dust bathe or to hang out and eat some more. In the afternoon, I put them in the 25' x 5' auxiliary run which is lined with fresh grass clipping and sprinkled with BOSS and meal worms, or let them free range in the yard. At first, she would just sit on the ground or in the dust pen, whenever she could, she would fly out to stand on the coop. Eventually, she could not resist chasing after the treats.
I kept moving the flock back and forth between two runs or letting them free range to keep them occupied throughout the day, anything but to let the Miss Broody get back into the coop. At night, she slept in the nest box, but I put her back on the roosting bar before midnight. She was very docile as always, puffed up a little in the nest box when she saw me coming to move her or the eggs, but I can pat her all I want, gave her lots of hugs while moving her.
Good thing the weather was nice and I had a long weekend to deal with her. I guess persistent pays off. This morning, the coop door remains open, but she stays out in the run scratching as usual now. Keeping my fingers crossed.
