Flying

So this week we had a shock our female duck fudge got off the ground by about a few feet, today we had to cover the pen up again as Donald flew out of it via the steps to the pool . Then tonight angelo got off the ground too they are black swedes we still waitin to for guy to come n start our bigger pen they are giving me a heart attack everytime I let them free range which I do about 3-4 times a day they are just 12 weeks old I just hope they get no higher in flight lol
