Hi this is my first time on here. Im new to the entier cockatiel thing. At home i have 1 femake whos name is kiwi and 1 male whos name is guava. I got kiwi about 4 months ago and its been going great. Guava on thr other hand is quite new to the home. Lets say at max 1 month. At first everything wsd great. They got along. Sort of. Guava didnt have much of an interest in kiwi so he hanged put with me most of the time. Now he acts like he hates me. Whenever i come near him he runs to me starts bobbing his head up and down whilst making that baby growl noise. I dont understand why since everything was fine. I tried giving him food water attention but he didnt want any of it. So what Does, he want??
