Just got a female breeder swan to go with my male. They meet in our barn and can come and go at free will. Its been 4 days now and they havent come out of the barn to the ponds, Is this normal for there ages and time of the yr. Seem to be happy and eating and drinking well. Will they come out when they are ready? Or do I need to take them done to the pond since this is a new home for them here?
