I went through the same thing with mine a while back. I was literally two seconds away from pulling the trigger, then thought about what I had invested in him (3 hours each way to pick him up), my end goal of getting darker eggs, & the fact that I'd have to go on a search for a replacement & start all over again, so I backed down. Besides, I didn't want to do something in anger that I'd regret later...been down that road too many times already.
That was about 6 months ago. Since then, he's been a perfect gentleman, with a single exception; when he & all his ladies were in the coop for the night & I was cleaning out the track that the door slides in, he half-heartedly pecked me. Other than that, he's been no trouble, in or out of the run.
