Why do you think she wasn't eating? Did you have her housed in a way she couldn't without eating what you had laid out specifically for her? Before a hen even starts to lay she accumulates a store of fat. That stored fat is mainly what a hen lives off of when she goes broody. That way she can spend her time on the nest taking care of the eggs instead of going out to look for food and water.1. She wouldn't eat the first week
I had a hen leave her nest twice a day and stay off for over an hour each time, eating drinking, pooping, and taking a dust bath. I had one that came off once a day every morning for only 15 minutes. I've had several I never saw off of the nest but I knew they were coming off because there was no poop in the nest. Are you sure she wasn't eating or did you just not see her off of the nest? By the way, all of these hatched fine.
The way I manage this is to collect and mark all the eggs I want her to hatch and start them all at the same time. If there are any others there when I start they become sacrificial and are cooked and fed back to the flock. Then every day after the others have laid I check under her and remove any that don't belong. As long as you remove them every day you can still use them for yourself.2. She had too many eggs
3. The eggs weren't the same age
If a hen is full-fledged broody there is nothing wrong with picking the hen up and setting her on the coop floor when you are checking under her. They typically squat there for a few seconds then either run off to eat, drink, poop, and such or go back on their nest. It might make you feel better about her eating if you see her run off but I don't feel it to be necessary.
What does your nest look like? Was it so shallow that it was easy for the hen to scratch the bedding out? I had to raise the lip on my nests to keep the hens from scratching bedding, real eggs, and fake eggs out when they were just laying an egg. Could raising the lip be a solution?4. The bedding wasn't good
Some broody hens will tear your hand off if you dare put it in her nest, but most of mine are more like yours. Some give a fairly gentle peck or two and that's it and some don't even bother doing that much. I typically put the back of my hand under the broody and lift her up so I can check the eggs.i didn't know broody hens aren't always aggressive, mine was very kind and is now one of my favorites![]()
