HI, I'm new to this chicken keeping lark, and was after some help. My Bovan Nera is about 24 weeks old, started laying at 17 weeks, and seems to be broody. She's sitting in the coop all day but does sprint out when I open it up in the morning. I've checked all the normal things, and she seems healthy, she's just reluctant to leave her coop. I've had no decrease in egg production (have three hens and get three eggs a day). The other two are not affected at all. I've been picking her up and locking her out today (quite to her annoyance) and she's eating and drinking normally. Any suggestions? I'm paranoid something is drastically wrong, and I have missed it!
