Hopefully the change in environment will do the trick.They haven’t had scratch since winter, I was giving it to them to keep them from being board and it didn’t help the boredom. I’ve upped their protein with kalmbach feather plume and it didn’t help and gave them diarrhea. Now I’m just adding catfood as a small treat here and there. They’ve always been on kalmbach layer pellets. Right I’m concerned that it’s too far past fixing at this point because I didn’t know what the issue was for so long and was just trying thing one at a time to see if it resolved. My run is small, but we couldn’t go much bigger due to ordinance, but once we rebuilt, the size run I have now was $1000 to rebuild to completely seal any access size down to 1/2inch. Even underground. Dang birds! I don’t want to give up on them but I’m also not rich. I’m hoping their new home will be what they need.

If not, don't feel bad about culling them, sounds like you've done about as much as you can do for them.
