I have a pilgrim gander that is guarding two females on nests. While he has always been rather I'll-tempered, he is quite vicious now. In the past I have always stood up to him and made him back down (e.g. Grabbed his neck, hissed back at him, held him down, etc...whatever non-harmful tactic that I could use to make him back off and establish me as "head goose" ). They are in a large run (16x75), but are a nightmare to feed and water. Should I still "show him who is boss", or is I asking too much of his natural instincts for protection?
