Hi All, Two birds in the loft looked particularly off-colour this morning, resembling fluffed-up balls of feathers, didn't show much interest in their morning feed. They are both young birds - approx. 6 - 8 weeks old. On further investigation, I discovered some really green slimy droppings on one perch and some more watery green droppings on another perch, there was what looked like some undigested seed in one of the droppings, although I don't know what end it came from ! I have removed both birds to a separate compartment and into their own separate nest boxes with access to water only. I have not fed them since. Both birds were recently treated for worms, but that was more than a week ago. I'm sure that this condition only appeared, at the earliest, sometime yesterday. Since segregating them, the droppings of both birds haven't really changed, just less of them I guess because I haven't fed them. All other birds seem and look fine, flying for nearly two hours this afternoon, albeit with the help of a large Sparrowhawk during the later stages of their regular exercise ! Anybody got any suggestions as to cause and cure. Many thanks, Steve
