2 year old green cheek conure being aggressive randomly
Hello, I have a 2 year old green cheek conure that we have had since about 6 months old. We don’t know the sex however he/she will have a good day a few times a month where I can hold him and he will lay with me play on his perch with me. I will give him/her treats and try and bond as best I can. He/she seems very territorial of the cage and have even caught him humping one of his/her bells that hang in the cage. He/she also sleeps up against this bell. He/she eats great and is in great health(as per the 6 month vet check ups)and I just want to establish a great relationship with my bird. When I dony get the lunging crazy biting behavior in the cage. He/she can be so lovable pressing up against my hand or neck and eventually pressing into my neck and going to sleep. I don’t know if the cage is creating some territorial tendency or if it’s a hormonal response. Any information would be very much appreciated. Thanks!!
