my muscovy drake is 4 months old and up until now i’ve had no issues with him being aggressive. i should also mention he is the only duck i have. he free roams the backyard now that he’s big and has become very territorial and attacks me when i go out to clean or feed him. he leaves bruises and cuts all over my arms. i read online that it’s best to hold their head down until they submit to show dominance but when doing that, he bit my face and wouldn’t let go, until someone else had to pull him off. i don’t want to result to rehoming him but i also don’t know how to help his aggression as he was such a sweet boy up until about 2 weeks ago! please help!
