Now that we have two "accidental" roosters, I wish I still had my broody hen, a Buff Orpington. Her broodiness was triggered by only three eggs, so if I didn't get out to the nesting boxes often, she started setting. Since that meant she stopped laying, I was displeased with her and put her in time out -- the chicken tractor where she could not get to the nesting boxes. It took days to break her brood, then back to the flock she would go.
Oh, to have her now. We want to try to raise our own chicks and we need a hen to do it for us. But none of the girls are broody like Buffy, may she rest in peace. I have heirloom breeds that have broody tendencies -- Black Australorp, Delaware, Barred Rock, Silver Laced Wyandotte -- as well as an Ameracauna that pecks at me when I gather eggs, but no one who won't leave the nesting box.
best article I found), we placed plastic easter eggs in the boxes, 7 eggs each in their 2 favorite boxes. We painted them first since chickens can see color; I didn't feel the neon pinks, blues and greens would fool the girls. If we can trigger a brood, then we will place her in a secure location to hatch the eggs, a place where the chicks can arrive safely away from the rest of the flock.
