ok ive hatched 7 swedish ducks and i have had 4 unexpected deaths and they have all been black ducklings and they have been very unexpected ill go in to give them water or give them feed and then maybe a half hour later i go out there and i have a passed away duckling and there have been no signs no symptoms pre mortem and no indication of cause of death post mortem so i have no idea wat is killing off my ducklings i thought maybe it would be a lethal gene but im not aware of any in swedish ducks......i have 3 left 2 blues and a black and i only had one egg layer at the time and that was a black duck and i had two drakes in with her so the blues arent the black drakes so i wondered if it was a black x black problem?????? im not feeding medicated feed and i water them 3 times a day and the are plenty warm so i dont know what is causing this and it is really destressing b/c this is my first hatch from my ducks and im about to die b/c i cant keep them alive but i dont think the problem is me though! any help in this matter will be greatly appreciated
