I sold 9 quail to someone, thought there were only 2 males but there turned out to be 4 (young A&Ms) but in any case they had spent a month or more together. Once the customer brought them home they actually got more space and were split into 2 groups. I started getting emails about bloody quail. Partially I imagine it was because the ratio was off but these guys had been pretty peaceful in a space that was frankly too small for them as they matured. What are some triggers that make quail go violent? The female that lays the biggest eggs is somewhat violent, she pecked the eyes out a male once. But since her eggs are so big I tend to incubate them. Is violence hereditary? edit: before I sold the group they were already laying and mating so they didn't mature after being sold.
