Hi, I have 2 silkie hens and a very large run. I was considering adopting 2 Muscovy ducklings that are still not feathered in but I can tell one's a drake/ones a hen. They were rescued orphans and very friendly. I live in town and if I got a duck/ducks wanted to make sure they were very quiet which I hear muscovies are ? My other questions are: Will they be ok with my silkies ? I was hoping that if they are young and brought up with them it might work ? I let my hens free range in my yard while I'm around to watch, Can I let them free range too or will they fly away (I have a 6' tall privacy fence) ? Would one muscovy be ok (hen), I'm concerned about getting such a big duck in a drake, but would be concerned a duck would be happy if the sole one ? do they need a pond to be happy ? Thank you for any input.
