PSHH! why reward the offender?!

(that's to the bully, not you

)
That's the opposite of how I would go. The bully would be in a time out pen. Possibly even out of sight from the flock for a couple days... so when he returns he can be the one to work his way back into the pecking order.

Why should the many pay for the transgressions of the one?
@ChickenCowboy02 are your boys with your girls or separated? That's way too many boys if they are together with your girls.
Also, have you read previous post about having plenty of space and visual barriers for them?
Glad he came around and started eating and drinking. Having a little experience and knowing what to approximately expect takes some of the worry out of different situation.

With any injury or trauma for the chickens, it may take them a little while before they came down enough respond to their bodies need for nourishment. So it's important to give them a little while before giving up.
