My roo has been a good father, but he has 3 hens and lived in a small aviary when they were broody, so when the first hen got broody he still had the other two to keep him entertained. And she was a *****, if anyone came within a couple of feet from her nest, she started chirping, clearly telling them to get lost. She wouldn't be suited to brooding in a small cage with other quail around, but being together with two more hens, her high aggression levels were great, as it prevented the other hens from laying eggs in her nest and messing up her incubation. She hatched her own eggs twice this year. Once they are hatched, daddy is allowed to help keeping the chicks warm. At one point, all 3 hens were incubating at the same time, daddy seemed to get quite bored, but one of them let him spend the night beside her
I went and bought 2 new males a couple of days ago, to pair with 3 of the girls that came from all this broodiness. A nice tuxedo roo got 2 girls and a tiny little blueface got one (she is about twice as big as him, they look really cute when they sit beside each other). The tuxedo is already trying to mate with his girls, the blueface seems content just sitting beside his girl. I guess the blueface might not be quite mature yet, but the difference in behavior might also be caused by the fact that he lives outside with a current temperature range of -5 - +10 degrees Celsius, where as the tuxedo lives in my room with an average temperature of about 15 degrees Celsius (my radiator doesn't work so it's quite cold). I haven't seen daddy mating his girls either recently, and they also live outside.
But that brings me to 3 breeding groups, I hope the ones in my room will start laying soon - and possibly go broody, I don't own an incubator and don't want to use it anyway - the parents that live outside haven't been laying since august and I don't expect them to start doing so for the next 3-4 months.
Good luck with your girl!
