Oh those teenage times. LOL that would be awesome to have 7/4 ratio.I am pretty sure that there are 3 ganders plus Sting (the father) so that would be 4 ganders and 7 females which will be just fine. I think I can manage that without getting eaten alive. The ones I am pretty sure are female are already beginning to develop lobes on their belly which I am taking as a sign. They play together all the time but they are at that age where some of them will wander off away from the others. Sting will give a honk and everyone comes running together so they are a gaggle for sure. Now and then they will all take off running across the field with their wings out. Wish I could get them to do that on cue so I could get a picture but they are not the most cooperative bunch.
