If your ratio is not right, no time out, ACV, or intro time will help. I’m not sure if I’m understanding the numbers correctly though,
1. how many total quail do you have, and what are the genders
2. How many are you trying to integrate together, and what are the genders
3. what size is the space you are trying to integrate them into
I’m not sure if it was that you are trying to integrate 7 males and 2 females into a larger group, or are you trying to keep 7 males and 2 females together in total? If that’s the case, you need to put 2 females and 1 male together and put the rest of the males somewhere else until you sell them, eat them, or get many more hens. Your males can hurt or kill each other and the hens, and giving them bad experiences will make them harder to integrate into a larger group later. Perhaps for now you can put the 2 hens alone in the brooder and the males together in the larger space?
