My poor chickens seem to get one sickness after another. Scaly leg, Fowl pox Infection bronchitis After the last illness they have been 100 percent healthy for 2 months. But today I noticed my rooster has one watery eye. I looked at my other chickens and they ALL have watery eyes (mostly only one eye). They have no other symptoms. The watery eye is only very slightly swollen and its hard to spot unless I compare it to a good eye. They are not scratching at it. There have been lots of mosquitoes about so I am wondering if its something they caught from them. Any idea what this is? (they have hatches out a lot of chicks this time and all the chicks and pullets are not effected - only the adults).
