Topic: Tips for fighting geese.
They can hit pretty hard with their beaks. Just remember to maintain eye contact. That is probably the most important rule when facing down a goose (or any number of them, they like to fight in packs). Also another important strategy is to spread your lats out, this will intimidate them. If the challenge is accepted the goose will spread its wings out as a sign to commence battle. The best way to start off the fight is to run straight at it and flap your arms while still spreading your lats (hard to do, but easily accomplished with a few weeks training). The goose will either be scared off at this point, or ready to take you on. If the latter is true, prepare for a long fight because once a goose decided to attack, he's in it to win it.
Geese are natural born bullies. They will bark orders and expect you to follow them without hesitation. Don't give in to this. If the goose is hissing at you, hiss back. If it raises its wings in a threatening fashion at you, raise both your arms in a similar gesture. You are representing yourself as a bigger goose and the bully will back down. If you have a gander that is aggressive and he comes at you ready to fight, don't run, don't back down. Just grab him around the neck and if he slaps you with his wings, slap back. You are the bigger goose, and he will have to back down eventually. Once he figures out that you are the one in charge, it will go much more smoothly.
