Bummer! I'm trying out a first-time broody myself. So far she's sticking to it...even let me know when I got too close (ouch! my poor finger!)
Been there done that too..that's actually how I got started incubating. Someone had said, best have a back up incubator, they don't always stick to it. Well this little stinker did all the way, until they pipped. Guess that freaked her out. She flew the coop! I had to take pipped eggs in and hurry and get that incubator warmed up. Got three babies out of the 5. I was hooked!
I give up trying to figure out what she's thinking. I went out to gather her eggs and put them in the bator and she's back on them, flat as a pancake, growling at me lol. Last night, she went up to the roost and I had to put her back on her nest. Not sure what she's doing but maybe I just happened to see her every time she was off the nest today. Oh well. If she fails but still wants babies, I'll give her a couple when the ones in the bator hatch.
