Confusing livestock with "pets" is a problem that often comes up because people aren't clear about why they are buying their animals and generally haven't done their research about the animals and breeds in question.
In your case, too many males in one "cage" will fight and kill each other so, do you want to dispose of their dead bodies or eat them while they are still tasty?
Or, do you want to become a bird "hoarder"?
All it takes is a bunch of cages to keep them separate so they don't kill each other.
How any "pet" quail does one really need anyway?
No offense intended but, I see this issue pretty frequently with hobby farmers/ranchers and suburban'ites. Oh, its cute (kittens, birds, goats, etc.).... Can I keep him/her? Months later, what to do when they are causing problems?
It is just like watching a Disney movie and running out to buy that Dalmatian or whatever fad pet is on the big screen. It rarely ends well.
I showed steers in high school. I never had any illusion they would die of old age in a nice serene pasture. Sure, I treated them like pets, brushed, washed, walked, etc. them everyday. I carried warm buckets of water to them in the winter and many other similar things to make their lives better. When the show circuit ended for them, they were butchered. No if's and's or but's about it. They were livestock, and not breeding stock at that. My heifers made it to the pasture though and lived a good quality of life (as long as the gave birth to calves
). The "soft hearted" in my family could choose not to eat meat but me, I loved every bite of my "pet" steers because I put the effort in to making them the best tasting beef I possibly could.
