Hi all, there are 2 of my quail that seem to have some sort of phlegm in their throats, with some clearish eye discharge and this kind of cheesy nose discharge, that I have cleaned out with a toothpick. I have tried to smell their breath and it does not smell, so I'm kind of ruling out coryza, I'm thinking it's Mycoplasma Gallisepticum? Egg production has dropped, but they are now quite old, around the 3 - 3.5 year mark now, and they haven't been laying for a while. One of them seems more major than the other, with crusted discharge around the corners of the beak which I have cleaned off. There is one male quail within the same enclosure, but he has no symptoms or issues at all. Any solutions or ideas would be greatly appreciated, thanks in advance
