It seems their behaviour changes drastically when they turn into adults.
My imprinted goose, Keld, also used to follow my every footstep - when he was a baby. Now, he follows treats.
Luckily, he'll do almost anything for treats, so I've used them to kind of train him all over again. When I want him to follow me, I (very patiently) hold out treats. When he's diapered, I lure him close with treats - and he seems to have learned to expect another treat right after the diaper is on. Which sometimetimes makes him search for that treat
during diapering...
He too doesn't enjoy being carried anymore, but he mostly accepts it on short-term basis - and he always gets a treat right after I've put him down. Then I'm usually able to pick him up again and start over.
He hates it if I try to catch him - he seems to be frightened of my flailing arms, especially if they're above him - but if I sit down close to him and lure him in with a treat, he accepts being held.
I often give him a treat and just let him go immediately, so he won't connect the treats with me trying to get him to do something he doesn't want to do.
The treats he likes are puppy kibble. Or really anything crunchy: cat food, breakfast cereal, pills(!), chips, crackers, but the vet says that puppy kibble is better for him.
I always have treats in my pocket now, which makes emptying pockets before doing laundry essential!
The only disadvantage is that he
has made the connection between pockets and treats. So even if a complete stranger puts his hands in his pockets, Keld will go up to him and start yanking at his pockets. I tell people to just hold out their empty hand to show Keld that they don't have anything - and it works - but most people don't really want to hold out their hand to what they perceive as an aggressive goose.
