I think moving one of your smaller coops in the big run is a wonderful idea. If your chicken is stressed from isolation, he won't eat. Being in the same area should work perfectly.
If your chicken realizes you are handling him to feed him, I suspect he won't be aggressive. That's how mine worked out at least - she was the worst at being handled (not aggressive but she would freak out) and now she's docile as long as it's me, the food lady. It took some time to get here.
Here is a YouTube video of a woman trimming a chicken beak that I found helpful my first time -
You can use a dremel, dog nail clippers, or human nail clippers. We rarely clip our girl's beak because she is able to eat mash fine with it a little long, but it just depends on the individual bird.
There also is an excellent Cross Beak support thread on this forum here. I tried to search for it, but for some reason when I click on search an Error is coming up, but it's a thread for special needs chickens that ended up being almost exclusively about cross beaks.
I did find a summary of the support thread through google: https://www.backyardchickens.com/ar...kens-including-tube-feeding-techniques.64321/
