Thanks ..yes took him today as noticed last night he was all puffed up and fell off perch few times but was unable to fly back up but was using his beak very awkwardly to climb back up and also I noticed his left leg he was not using he just did not look right..vet said it was definitely his leg as was not closing however gave him some liquid pain killer, I brought him home and he seemed unable to balance on perch and kept falling, I think it may have been neurological as he had not been fighting and he was holding his head upwards during the day. He died about 3 hours later
