I have 2 red hens and a red roo in the pen together. The 3 have been together since I got them. I have a large speaker box, with two large openings for them to roost in. It's raised high enough I don't think they would feel vulnerable in them. Both sides have fresh laying material in them. Both hens will lay in the same side but keep their eggs separated on either end of the same box. Neither one will sit on the eggs. Each hen has 9 eggs on her side. (18 eggs in there) Now here's the questions... 1. How long before they begin to sit on them? 2. Do they wait to have a certain number of eggs to begin to sit on them? 3. How long should I wait before collecting them? I have an incubator but there are 33 quail eggs in there and I wouldn't want the little quail to hatch out and get caught up in the turning mechanism while its turning the chicken eggs. How long do I wait?????
