My 12yo daughter is trying to start up a coturnix quail business to may pocket money but having trouble building up her breeding groups as she keeps hatching a large percentage of males. (and also having poor hatch rates, but that's another thread). Last hatch that is now old enough to start sexing there are only 2 obvious females out of 11. One is white though, so not sure how to sex that before it reaches maturity. They are 4.5 weeks old. And previous batch she only got 2 females out of 8! Have another just hatched batch so fingers crossed there are enough females in that batch to get things up and running. She wants two groups of 5 females to one male.
Is there anything that influences gender? Wouldn't be so bad if she was getting 50/50 mix or the opposite mix to what she is getting, but to be hatching so many males all the time is just frustrating. And they are harder to sell.
