Kris, If Chickie Hawk is that unsociable and you need him out of the way for a bit, you can drop a large and thick towel over him and bundle him up long enough to tip him into a pet carrier for a bit. He can take the towel in with him if he likes.Lol! How did you know the goats have been back around? A bachelor herd of Stinky Billies, no less. In all honesty I have to repair Chickie Hawk’s tractor, and they have been stationary for almost a week now. The mud still isn’t as bad as where I rescued them from though! But between the weather and the Boyo. DH Andrew said “and what are you going to do with HIM while we fix it? You don’t plan on trying to work in there with him, do you?!?”
I've had to do this with a couple over the years. If you're quick and have everything to hand it generally works well.
A rooster with it's blood up knows no reason. In the short term it doesn't matter why, there's stuff you have to do.
You have a bit of an advantage in that you know he is likely to act up. Often the 'rooster' problems are the surprise when people find out Mr Cuddles isn't so cuddly any more. I don't think given what I've read you're that sort.
I've assumed you are reasonably fit and mobile given you farm, coping with house build etc so the towel drop should be easy enough for you.
I sweep them out of the way these days. I get one or two that have another go but if you've taken them off their feet and swept them backwards a few feet, here at least most lose interest in the fight.
These days things don't get that far thankfully. All the new arrivals have a dad, and the dads and I have had time to come to a working arrangement. This gets taught to the newcomers and the dads enforce cockerel good behavior towards me.
However, I still use the sweep occasionally when I need to break up a fight.
Such good advice! I'm dealing with 2 cockerels just coming into their hormonal, "who am I what am I?" stage. I've had to set them straight on who's boss between them and me a couple times.
