Yeah I dunno how I would've "broken" him.. I had hatched Newt and Buzzard to raise them as pets, I didn't know if either of them would be drakes and I wouldn't dare to try and vent sex them since I don't trust myself doing that lol.
EDIT:
When Buzzard was a duckling, he seemed fine on his own so I didn't give him much attention, he "temporarily" imprinted on a stuffed animal I gave him since I didn't have time to give him as much attention as I gave Newt when she was younger (because of school) so I would hangout with him every now and then but when he started getting bigger (still didn't know his gender by then), he kinda seemed depressed and lonely and since they are flock animals and he was still too small to be with Newt I would hangout with him until he got big enough and him and Newt went together so yeah.
I don't think he imprinted on me right away, I think it was at the point he started to get lonely and since I would hangout with him he imprinted then I assume?
