I do not have a mature swan but I do have a pair of young is available if you are interested?View attachment 1980844 I have a healthy 4 year old male Black Australian swan that needs a mate. Do you have a mature female available, reasonably priced? Also open to giving up Gunther to a good forever home where he would be with a female. Price negotiable. Won't ship him so must be within driving distance of San Antonio, Texas.
