Anyone in the Baltimore/ Frederick, Maryland comfortable vent sexing geese? I have six african/african cross straight run goslings approx. two months old and need to know who is what since they are going to different homes-males to a friend-females stay with me. I watched the Metzger Farm video on vent sexing and although I am a nurse I think someone experienced would perform it in a manner that will be easier for me and the goslings! Thought with 100,000 Backyard Chickenites there may be help in my neighborhood.
