give away a chicken what steps to make sure he is in a good home

I have an orange rooster named nick and a white brahma hen. Basically I have 2 coops and he stays in one while my other newer rooster stays in the other with most of the flock. I gace him this one unwanted chicken i didnt really care much about with him and they are supposivly lovers or something Anyway i feel kind of bad giving him away but i need to becuase i dont think hes happy here and i dont really like him all that well most of the time he attacks me and puts crap all over my jeans. But i feel bad though usually like right now at nighttime at daytime i dont feel it and i can get rid of him but at night i feel bad. He needs to go the 2 roosters overmate badly and had holes dug into 2 chickens side's. My new rooster, dosel is a nice young fellow. He walks up to me and pecks me if he wants food i can pick him up and hell follow me. Very nice rooster i got him as a chick. So im going to keep him and give away nick and his "wife" but dont know how to to it well. I Gave away a red rooster last summer and im pretty sure hes dead by now becuase these were first timers.

I only got one call on cl ad i dont think hes interested depite him emailing me...

 

Ok but hes very mean thats what i said on cl im going to change that. Maybe ill keep him seperated until spring when more people want roosters. he is tamming down though
