I need help! We started with 9 adult quail (1 roo and 8 hens) and then hatched 35 babies. All went well with raising the juveniles and when they got big enough we put them in with the adults. There was no fighting and the hens were still laying great. Our quail pen is 7 ft tall and 12' x 12'. It is covered with a mesh tarp so that they dont hit their heads. We have branches for them to hide in and plenty of food and water plus a hutch for shelter. The birds did great together for about 2 months (6 months of having them completely) and then about the end of Aug the hens stopped laying and then birds started dying. 1 or 2 a day, one time 6. They have no marks on them. We check on them multiple times a day and they will die in between checks. We are at our wits end. All of our original hens are dead and we are down to 7 of the juvenile with 2 more dying today. We have checked for all of the quail diseases but there have been no eye discharge/ coughing/ or acting different. They seem perfectly happy and then dead. If you have any idea how to help us I would greatly appreciate it!!!!
