A bachelor pad is a common way to keep males with minimal fighting. Keep females away and make it big enough so they have room. Room is just as important in a bachelor pad as it is for any other flock of chickens.
I don't know what your goals are as far as breeding, obviously not for meat. It may be for show, for egg production, or to somehow play with genetics. I don't know how many you will hatch but a lot will be males. Depending on your goals a lot of females may be rejects also. Typically you need to raise them to a certain age to access their potential as breeders. If I knew your plans and goals it would be easier to write this but the point is that you will probably have a lot of pounds of living meat to dispose of.
It is probably illegal to dump living animals on any property without the owner's permission, whether private or government owned. There are several sound environmental reasons for that, let alone how that would be trampling on the landowners rights to manage their own property. If you can get the landowners permission by all means go for it, but dumping is generally illegal, whether what is being dumped is living or just trash.
Depending on how old those chickens are when you are ready to dispose of them you might try contacting a soup kitchen, orphanage, or some place that feeds people to see if they will accept a donation of live chickens. Not many will but you might get lucky. Your state representative or pastor may be able to help with this. Or maybe contact a zoo or some other place that could use your chickens to feed their animals.
Ethically I'd prefer to find a use for those chicken instead of basing my practice on an almost certainly illegal way of fouling the environment with them. But that is just me, I can't dictate your ethics.
