We moved to an acre lot on a pond and would like to get 2 ducks. Leanings towards Cayuga and/or Welsh Harlequin. I want sociable, relatively quiet and fairly good egg layers. My thoughts are 2 females (let me know if this will be an issue), and am considering 1 of each breed. Would that work? Or would it be better to get 2 of the same breed? Also- we live in Texas. Hot,long summers... is that an issue?
