This is currently going on with one of my Cochins and she thinks she's a dragon!! It's been 3 weeks now and despite giving her a good dusting she has a sore looking breast bone. I kick her off the nest (it's outside, set up for summertime living) and literally lead her to water! Then she eats a bit and goes right back on- hissing at any of the others who dare look at her. Should I try and break her of this? It's our first time with this gal but not our first broody- they seem to snap out of it after a week or so...
