I have seven new baby chicks! A 50% hatch rate. Not great, not awful.
Broody girl was still sitting firmly on the unhatched eggs. In the meantime the chicks were starting to get feisty in the nest box. Since it was two days past the hatching date and no new chicks had appeared in a while, I pulled the chicks out of the nest box and let them loose on the floor of the coop/run. Then I pulled the remaining eggs out from under the broody. (They were all duds.) She still sat there. I finally managed to pull her out of the box and plunked her down on the floor of the coop next to the chicks, who were already starting to run all over the place. Broody girl snapped into momma-hen mode and immediately started showing the chicks how to forage for stuff in the deep litter. Awww... I'm so proud of her. Looks like she's going to be a good mom.
Downside of having the broody raise the chicks in the coop/run: it's hard to avoid stepping on the chicks! Already had one get under foot and partly stepped on. Ouch. Good thing the coop has deep litter. The chick just sank down into the litter. For a minute I thought I might have to cull it, but it gathered its wits and was moving around with the other chicks a few minutes later. By the end of the day I couldn't tell which one it was. I think it's going to be fine, but I'll keep an eye out for weird limps.
The other birds didn't have a problem with the chicks. They did have a problem with momma hen getting all puffy and in their faces when they tried to get near their feeder. (I have the chick feeder under the hanging grown-up feeder for now.) At one point the cockerel scuffed with momma, basically putting her in her place for being so aggressively defensive of the feeding area. She took the chicks off to a corner after that, and everybody else got to eat. I will have to watch the dynamics and make sure everyone is getting enough food. Tomorrow I will make a special feeding area for the chicks that the big girls can't get into. Today it wouldn't have done any good - the chicks stayed under momma most of the time. In a day or two they will be more adventurous. Soon they will appreciate a grownup-free area. As long as momma hen remains nearby.
The cuteness factor is overwhelmingly distracting!
