I'll be putting my broody hen back in the cage shortly. sigh. She lasted about four weeks, then went back to her evil twin personality. It's amazing how hateful and aggressive a timid little hen can become when the voices tell her to sit on the eggs. Once you collect the eggs out from under her, she'll go out in the yard and hang out with the other two hens, so I'm not so sure how important it is to break her at this point.
Our neighbors had one who was very susceptible to broodiness and decided not to break her but to gather the eggs every day, thus getting her off the nest so she'd eat, drink, and get some exercise. She served as the intruder alarm whenever someone unwanted (snake, racoon, possum) would get into their chicken coop at night. They'd hear her squawking and hollering and they knew to get out there and take care of whatever was causing the racket. That said, I'm seriously considering letting LittleBird continue brooding for security reasons. Plus (and I know this is wrong of me) she's so doggone funny when she gets aggressive and protective like this, because it's the exact opposite of her usual personality! Usually if she thinks you might be thinking of touching her in the next few weeks or so she screams like a banshee (not the same as the squawking and hissing she does when you bump her off the nest) and runs off in the opposite direction.
