We have 13 runners, 3 welsh harlequin, 2 pekins, 2 black swedish and 1 blue swedish. We also have a pilgrim gander and 3 baby toulouse geese. I don't think they are that hard to care for. We feed and water them in the mornings, give them fresh water 2 to 3 more times during the day and feed them again at night. Theres just me and my husband and since we retried we enjoy them so much. I guess you could say its a hobby to us. They are fenced in almost an acre with an electric fence on the outside of the pen. We have 4 10' x 10' dog pens inside their area that we have installed a panel in the middle of each and now have 8 individual pens for breeding purposes. Oh and we have 8 hen and 1 rooster.
