We have a couple CG we tolerate, keeps a wonderful Father/Daughter relationship wonderful, as should be. 4-5 Goslings hatch each year, Turtles or 26" CC knock them down to two every year , they fly out with Goose & Gander in June each year, take the land mines with them , Thank Goodness. I admit , it's fun to watch them grow . No other CG use the ponds , G&G open a 55 gallon drum of Whoop-**s on intruding CG , wish they would open 5 -10 drums of Whoop-A** on the Cormorants. Your Pond is Beautiful , Best of Wishes with it's development .
