Hello.. I have two beardies Rosie and Augie. They live in two seperate enclosures however they do see eachother often. Augie is about 5 months and Rosie is about 4 months but do to sickness Rosie was a bit delayed in the growth however now she is doing amazing so Augie is bigger. We dont let them out together because when we did about 2 months ago Augie tried to eat Rosie's head so needless to say we dont want a repeat of that. Ever since then anytime Augie see's her when he is in his tank he becomes aggressive, puffs out his beard and repetitively tries to run through the tank walls to get her, and she arm waves. However, lately, he now puffs out his beard, it goes very black and he head bobs like crazy, really going for it, and she ignores him. To me it seems like he is now trying to impress her. I am not planning on letting them near eachother, however I am wondering if because now that he is older, he wants to mate and/or impress her.... Rosie doesnt really seem impressed, she was more occupied with the cricket she saw in his enclosure.
