10 females/2 Males per cage. Will this work?

[kabuky]

I've raised valley quail at two properties. I had some 20-30 quail raised together with 10 chickens. They all shared a horse stall (10x10) and 15x20 outside pen. I never had an issue with any of the birds. Now I have an 8x10' enclosure and one male killed 5 otherm males and now shares the pen with 3 females. After the killing spree, there haven't been any issues. I have 100% fertility. Now I want to add on a 20x20 to accomodate some 15 chickens and same number of quail. Big enough? or do you think I will have some fighting?
