Used my scope today to look at the birds feeding. Some chaffies have problems with thei'r leggs, the legs are twice normal thickness and look as if they have been dunked in concrete or porrige which has then dried to a white scab. No other symptoms and they seem healthy enough. I am aware of scally leg in cage birds and it's not that.I have about 30 feeding along with about 30 greenies which seem to be clear.
