It’s breeding season, they’re hormonal and are quick to anger, they can’t really help it. They should be settling down in a month usually.
Geese are very social, who spends a lot of time with them they consider their flock, because they have long memories it can take awhile to earn their trust, but once earned it can be lost if you don’t maintain it.
My advice is to start spending time with them, give them treats and just sit with them for awhile each day. If they charge or try to attack say NO! Then pick them up and carry them around for a little while before setting them back down.
It’s important to act like nothing happened after, further punishment or intimidation just reinforces their anger towards you. It will help even better if you then offer a treat. The entire thing teaches them that you are dominant but that you are also are their friend.
After awhile they’ll figure out what No means and make an attempt to behave.
Picking up a gander is easier than it sounds, but two angry ganders complicates things. If you have someone else there with you it will help, two people to pick up two naughty ganders, or at least someone to distract one while the more naughty of them gets picked up.
I have managed to scoop up one while there were multiple naughty ganders present but you need to be crazy fast and fairly used to it so I wouldn’t recommend doing it alone if you’re not used to it.
How you pick up and attacking goose:
Grab the stinker by the head just firmly enough to hold on but not enough to hurt him. He can’t bite you if you have his head.
Scoop your other arm around his torso to pin his wings and lift.
The faster it’s done the easier it is.
