Hi there, a couple of months ago, we discovered six dead birds in one night in our aviary. One was a budgie, and there were two finches, a bourke and a canary. All had had their heads or faces pecked or picked at and some had had their stomachs pulled at and had been bleeding. It was awful. We thought that we had had a rat invasion as we had been told that this can happen so we spent hours rat proofing the aviary and have had no further trouble until last night. This morning we discovered another dead budgie with the same wounds, face, eyes and stomach. The birds have been in the aviary together for just on a year and we have had no other trouble with any of them. Would this have been another rat or mouse or is it possible for another budgie to have done this. I only wonder because this morning one was sitting on top of the dead one pecking at it. It was disgusting. Can anyone help please? We are new to the bird thing, although have been doing it for a year, but never had any problems. Any advice anyone can give would be great.
