I have only 3 orpingtons. They have about drove me CRAZY with their broodiness. I get one broken and I'll be dangled if another one doesn't become broody. It is unbelievable how stubborn they are. They act hysterical if they can't get to the nest box. I have always checked the nest box at least 2x a day & took out eggs faithfully.. The one that is broody right now is a tough one. Meek little thing she used to be. I have removed all nesting material, blocked off the boxes (then nobody gets to lay). I have put her in cool water to cover the front of her breast. She is not having any of it. I don't have a cage but I am determined. I can pick her up and put her in the yard with her squawking at the top her lungs and trying to shred my hands (I started wearing gloves afte the first instance of that behavior. ) . I make her stay outside the chicken coop during the day. She and her sister have never roosted, preferring to lay on floor of chicken coop. This morning she came out with the others but if I even give her a glance sideways, she screams like a banshee. She hasn't made any attempt to go back in the coop today but if one of her compadres gets too close to her (I presume she has that distance calculated in her head) she screams and puffs up like the Incredible Hulk). I have the patience of Job and she will NOT win. I hope it will not hurt the others not being abl to get to the nest box.
