I have honestly thought about making a bachelor pen. I mean, I have another juvenile rooster who is 12 weeks old AND I hatched out at least 1, maybe 2, CCLB males a little over a week ago. There's also two other EE chicks that could possibly be males. However, my DH is in the process of building me a 3rd coop right now. If I asked for another one, I think he'd serve me divorce papers instead.... Funny, but not, ya know?
I do know what you mean though.... That's part of the reason why I have hesitated culling him before now. We've had problems with hawks and foxes. I have many chickens, including these two roos, who jump the fence to free range without permission. I liked having both roos around because it was double the lookout.
I also loved having 2 boys watch the flock. They got along great for 8 months. In our case, beta turned on alpha at the end of January. Alpha, a Brahma, wasn't going to back down but also clearly wasn't out to kill beta unless he had to. He'd put him down, chase him off, then go back to the flock. Can't say the same for beta, an EE. He was in it to win it, no matter how many times the Brahma put him down.
When it was obvious they weren't going to stop, I separated them, cleaned each boy up, and put them in different coops to rest.
I was looking for supplies for a cone and mentally preparing for the EE cockerel to leave the world, but the more I thought about it, the more I wasn't sure. Both boys have good & bad qualities. DH said to sleep on it for 2 weeks.
It's been, ohhh, 10. Still thinking it over. Things are copacetic in the meantime. The flock was 2 different ages anyway and fine being split. Sometimes all the ladies still get together, but there's no love lost. The 2 groups currently take shifts in the yard, but we're about to expand so will split the yard for future situations like this.
As far as the future, we recently decided to add straight run Marans in May, so there will be more boys in the mix, and now I'm reserving decisions on all males until those chicks grow out. It may be a bachelor or a freezer situation. Either way, all birds will have happy lives until the moment they leave them. Solving for the flock looks different for everyone. Good luck in your decisions!
