Rehoming day was today for the chicks I'm not going to keep. My two boys are gone

I moved all three of the broody's chicks out with them, too. I was originally going to keep the female for now, to use her for my integration purposes so broody can still have one of hers, and maybe take in the rest of mine to raise with it, but my recent observations revealed a worrisome pattern. The broody's boys attacking my chicks were prompting the broody to side with them and peck my chicks as well. I don't know if this is what ruined my chances with her or what, but she has started pecking my chicks preemptively when hers are around, even if they aren't fighting. I did an experiment. I put broody in the sectioned off area with just my chicks. She was totally fine, clucked for them, showed them food. Then I let her female chick in as well. With her own chick next to her, broody started pecking my chicks again! It seems like the presence of her chick was reminding her that the rest aren't hers. And this happened even without her males being present. So if the female wasn't going to help things, but keep making it worse, then there was no point in keeping her.
I locked the broody in the coop alone with some treats, so she wouldn't see me stealing her babies, and I put them all in a dog crate, in the evening close to bedtime. I hid the chicks in the basement out of earshot and let the broody out - she was very upset - and distracted her and the other hens with a bunch of scratch and fresh greens. That seemed to keep her busy and quiet until bedtime. Right now she's sleeping on the roost with her friends, for the fist time in almost two months.
I drove the chicks to my friend's farm after dark. I'd made a MHP for them, the same as mine, and set it up in a division of her giant farm coop. My boys knew what to do, but it took the broody's chicks some cajoling to stuff them under the MHP and keep them there. Being broody-raised, they are incredibly flighty and terrified of people, sadly, despite my presence in their lives and their mom's efforts to lure them into my lap. While I was wrestling with them, my boys came out, made themselves comfortable in my lap and snuggled in, ready for bed


They were so relieved to see me there in that strange new place... It broke my heart. And it will break my heart again when the time comes to eat them. But such is life. We have a date to go visit them on Sunday with the kids.
Now we'll see what broody has to say about my three girls tomorrow...
