I have mini australian spotted ducks and mini silver appleyard ducklings that I am picking up today. 8 total. So...I want them to stick around. They'll be in a fenced in run with a fenced "roof" on the run, BUT I would like to be able to let them run around our yard while I'm outside relaxing. I don't want to risk them flying away. Would you clip a ducks wing? If so, how?! Is it the same as clipping a chicken? Also, I have no clue on gender. I'm giving my next door neighbor three and would like to give her a trio. Most were hatched at the end of April. Should I be able to tell the gender at this point? And I was told she can't tell the two breeds apart. Any tips for doing that at this point? Assuming I kept the two breeds together, could they successfully breed and have babies at some point or would they be mules? Thanks so much!
