I have 10 coturnix in one large coop/pen, 8 hens, 2 roos. I have 2 roos in a seperate bachelors quarters to keep the hens from getting chased so much. First egg was layed 4 days ago Thursday on the 1/2'' hardware cloth. Since that initial egg, all others have been layed in the nest box I made for them. The nest box is 8'' X 8'', 6 sided with a 4 1/2'' hole cut into one of the sides and hay thrown in for the nesting material. Nest box is placed for easy egg retrieval. Oh and our temp here is 114 high today and 85 low, and they still lay. I'm impressed! I was not certain that they would lay in the nest box. However they love it. Even the girls that are not yet laying have showed their interest and nesting nature by using it every day. I will say I like the aspect that they are keeping the nest box free of their poop and thus the eggs are clean. For sanitary reason I like the nest box, however I'm not sure they will keep the nest boxes clean like chickens do. So here is my big question. How many nest boxes should be or could be used each day for 8 laying coturnix? And how many people go to the effort of giving nest boxes to coturnix? Are most having them lay on wire or slanted wire for easy roll out?
