Sorry for blocking up the thread, it was early for me and being new to ducks especially, i tried to put out everything..
the pair i have are from several domestic ducklings bought and put or turned loose in his barn. he hasn't answered my txt asking what he fed them, and there was nothing around but weeds n grass, goats and mud aside from dead ducks. no food water or dished even asid from corn for roller pigeons in cages. I was wondering about getting feral scovie eggs to put under this female (they are mostly white with light brown).. as have one egg they care for and watch over, but haven't set on or laid any more eggs in just under week I've had (male is pulling feathers and i was taking them out of spot he chose in depression in middle of coop and putting in nest box, and now he seems to be putting there too). they seemed healthy generally, just not too strong with broken and ratty feathers that get and stay soaked quick, and can't seem to fly or male walk well on one of his legs which is slightly discolored swollen and looks like dog may have had at. they seem to enjoy pool but not wanting to go in though do spoon/bill it all over selves and onto each other. they seem to be getting used to me and not scared but not friendly or mean either. they both now just stay at times as i go to, even letting me touch and pet at times after grabbed and showed wasn't going to try to eat.. lol. i can have my rough collie herd them back in pen if need be free range, but don't want to stress any more than have (before got, bringing home and trying to set up pen few times till got were they seem should enjoy (rotting moss covered bug heavy logs and stumps they seem to love hanging around billing at). i know nothing of scovies hardly, can't find much on except to treat as geese or mallard typ ducks, that know some about mallards and canadian geese, but these seem so differant to me (and quiet and hard to read body language)..
