I had 2 roos,they both were sweet, tame and run to me when I called their name.  I raised them and spend a lot of time with them.
The older roo did attack us here and there, but not often, so it is to show they are not like dog and cat.
The older roo attacked me whenever I try to take a picture of him or talk on the phone. He hates phone period!!!
With my flock I found that roosters are friendlier when they are little, they show more personality than the hens. Hens are more friendly once they start laying eggs. My roosters were sweet and they sat on my laps let me patted their feather, put my hand under their wings..they don't mind.
It is hard to rehome roosters and you just don't know what kind of life they have once you send them off.  I rehomed my young rooster to an animal rescue farm for a month, I had to take him back as my mom was very upset. When I got him back I found that he was very sick and they did not look after him. I no longer rehome animals in my care, I euthanasia them if I can not care for them anymore.
