I hear this a lot from people. I would do exactly the same on a single acre plot. The space is great, it allows me more flexibility in how I manage the chickens here and it allows for more chickens.If one has a lack of space and no one to give chicks to, having broody hens hatching them out makes for tough decisions as to what to do with all the excess chickens. This has been true for me, so I just didn't have roosters. Things are changing here and I'll have a large enough coop to accommodate broodies and their babies, so I'm keeping my two cockerels. We are not all as lucky as you with all that space and freedom.

I know quite a few people who have a similar arrangement to mine with small plots. So, without wishing to offend, it's the attitude, not the size of the plot of land.
From what I've read of your setup I think you know this. You are, despite the difficulties, managing two cockerels in your flock. So not only can it be done, you are doing it.
I don't think DobieLover here has a large plot but she manages not just broody hens but roosters as well. My elder sister has less than half an acre and has done the same.
