Hi i have been breeding Japanese quail for a while now but recently have suffered a number of fatalitys. I've been going in the aviery to find a number of birds dead. Previously they all seem to be in good health happy eating and drinking as normal then by morning they are dead, i found two who were barly alive there heads laying to one side not being able to hold themselves up i took them inside gave them drink but they were to far gone and passed away shortly after. I have lost over 10birds now ranging from 4weeks upward in age and am at a lost as to what i can do as there is no obvious signs of what is wrong, we inspected the bodys but found no injury marks anywhere so dont think its due to fighting as we have never witnessed this while observing the birds. If anyone can shead some light on this problem for me id be most greatfull as where i live we dont have a decent poultry vet and they seem to be dying to quick for me to take them.
