My Africans and Chinese have started to get some lift in their flight. Today they were in the pasture, which has a number of berms, and saw me coming out so of course started running towards me 4 of the 5 got some air about 6-7' off of the ground and 2 flew right over the pasture fence. They probably got about 75' of flight. Will clipping a wing stop this from happening or just make them more lopsided? I am worried that they will fly into the fence and injure themselves. 3 were able to turn and land before the fence but I was scared they would fly right into it. Thanks.
