I got my first black swan this past weekend (male 3 years old) and I will be picking up a female next weekend (will be 2 in the fall). Right now I am keeping him in my catch pen with my waterfowl and we are trying to decide if we want to build them their own avairy or if we let them go if they will hang out on our pond. We have wild mallards (and oterh ducks) and geese the fly in and out every day and the pond is around an acre with an insland in the middle of it. It is stocked with catfish. I also have Sebastobol geese on the pond and a pair on Pintails that escaped from my pen. Any advice would be great..
