This is Coco Chanel (named for the designer). She's a sweet cochin, all black with a "necklace" of white around her neck. Her head is bald right now, as the roos were after her before she went broody. Today, I've brought her inside the house in this pet crate with food and water, no litter, just the bare floor.
Coco has been broody now for WEEKS. I've been attempting to find her "reset" button by removing her from the coop many times a day, walking around with her, even taking her up into their fenced pasture, a ways from the coop, to see if she will stay and scratch around and forget about being broody. She scratches a bit, poops, then runs for the coop like the road runner! These maneuvers worked for 3 broody hens before her, but not for Coco.
I've even tried the frozen water bottle under her a few days (nope, she keeps moving it). It's not warm enough here to give her a cold-water chest-dip.
She's becoming ridiculously skinny, it's time for bigger intervention. I don't want her to starve herself to death, which I'm concerned she's on her way to doing. So my questions for those of you with stubborn broodies:
* Will keeping her in this crate, plastic floor, no bedding, with food (right now she has some scratch grains, meal worms, and a bit of banana) and water for a few days be enough for her to forget about being broody?
* Is there anything else I can do for her in there?
* Is there anything I am missing/don't know that could help her? (For example, feed her anything special to help her gain back some weight?).
She's a REALLY stubbon broody girl! Thanks for any insight, advice you can share!
