Well, I spoke too soon! My buttons just started laying:yiipchick
SO far we have three eggs in three days from one, and none from the other female. She is really a nervous one, so who knows.
I feed mine turkey crumble, as I was told to by the owner of Bracken Ranch, where I got my button quail eggs. I also feed seeds scattered around the floor for them to search for, greens, meal worms occasionally, and try a variety of things as I think of it. I will feed eggs to them as I get around to it, I think.
The animal feed store recommended game bird feed also for the button quail, as it is about 22% protein.
I also make sure they have grit and calcium in a variety of ways, and finally I make sure they get a dust bath several times a week.
Good luck!
