We have 5 quail. 2 that came from iffy conditions and 3 that were well cared for. (One had bumblefoot and they were both bald on their backs and head and their feet were beat up) Our two original girls had laid 1 good egg and a few soft ones before we tried to integrate. Integration didn't work out so they are separated again. Out new trio is doing well. We get 1-3 eggs from them. The other two have big spaces in their laying pattern (I am not even sure they are both laying) and the eggs are basically just membrane. Here is a picture for comparison I know this is usually a calcium issue but we are giving lots of oyster shell, probiotic/electrolyte mixin the water, gamebird feed (with a bit a bit of chick starter this week)..could there be something wrong with them?
