We have three parakeets... recently we have noticed that they are scratching more and even occasionally rubbing their necks on the cage. We clean the cage often. We upgraded their cage - We got a BIG pre-assembled cage from a pet store. Could the birds have gotten mites from that cage? I heard it is hard for home birds to get mites and I can't figure out how they would have gotten them. Speedy has a red patch on her stomach and I'm very worried. Our birdcage is located by a sliding glass door that we leave open (Screen attached) and outside birds often come by to chat with our birds.. Could they have gotten it that way? We've had our birds for a year and absolutely love them. Should we get the mite spray or am I overreacting? I would appreciate any help. Thank you.
