Everything is still going well with Baz aside from two quarrels. The bigger of the two was May 25th (Day 15) and I think that was because he knew something was up, which was that I was in early labor. (Yes. I've been beating him up while nine months pregnant and I have the physique of a twig with a basketball under my shirt. I'm sure it was hilarious for any potential onlookers.) We had a pretty big "fight" where he landed no blows and even came back for seconds after hiding under a tree. I was ready to just give up on him at that point because that was ridiculous.
Two or so days later we had another small fight when I got home, but he was quickly subdued and didn't try again.
Since then, he's done a small run or two at me, but otherwise has taken to ignoring us. I think the new tiny human threw him off for a bit, but in the two weeks my newest squish has arrived Baz has calmed remarkably. I do still occasionally threaten him with my hand, but that's all it takes now. I can let them out and he goes on his merry way with the hens. If I go near the coop he gets a little wary, but remains respectful of my space just as I respect his. If he tries anything more, a couple pats sends him away although I still follow him a small distance while patting his back to reaffirm my position.
All in all, I'd call it a success. I can go outside with my kids with peace of mind that he's not going to come running out of the blue to pick a fight. I still listen for him to run up behind me, but he hasn't done much in the past week to warrant more than that.
