You spend time with them.
Yes, probably not as much as a lot of folks do, But once mom is done with the little ones, I try to get them used to me being around, handling them, giving them treats, etc. The little boys learn that if they peck me, even as fledglings they are going to wind up flipped on their backs in the palm of my hand until the pecking stops. Once they are around 4 months old I'm strictly hands off with the boys. I may hand them treats but they do not get handled unless they are sick, injured or are stretching the limits of their rooster behavior. They are not pets. True, I do have favorites. I think we all do when it comes to our birds.
At the moment I'm having to spend a more time around the coop and run as we are renovating an old shed into a bigger living quarters for the flock. The joy of old sheds is that the more you do to them, the more you find you have to do to them. Today I was outside, sweating blood while rebuilding a wall so we can proceed with metal siding. Because I was outside, I got to hear 6 month old Junior (son of Red, the Buff O rooster that died last month, and the mirror image of his dad) crow for the first time. It was pathetic. Probably the worst first crow I've ever heard a rooster make but I was giggling like a school girl at him and was thrilled that I had gotten to witness it.
Usually I see the flock in the morning, handing out bread as I turn them out into the run for the day, then around 2 when I check water and usually about a half an hour when I turn the coop bedding, do water and food and give them a general check over to make sure nobody is sick or injured. If I wasn't retired I wouldn't have this pleasure. Also the coop and run are conveniently located so we walk by it frequently during the day so they get tossed treats. If we don't have treats to give them there is a row of little faces giving us the stink eye lined up at the fence. We have been know to make a special trip back to the house to grab something to give them as a treat.
They train us quickly.
Are they livestock? No not precisely but they do live on a farm and I have grown too attached to them for them to be considered livestock. Are they spoiled? You bet. Am I enjoying spoiling them? Yep.
