For my starter ducks I checked craigslist in the fall for people thinning their flocks before winter set in. I got a free runner, khaki drake and a khaki hen. A few months later I got a buff for $6. The runner provided me with a wicked amount of eggs over the last 2 years. She also turned out to still have her brooding instincts in tact. She raised a clutch of 10 ducklings this spring. I recently sold her for $10 to a petting zoo who wanted a good broody. (She was a great farm duck but for my small lot, she wasn't tame enough.) I sold the Khaki drake and the buff hen as a pair for $20. Janet, my khaki hen, was injured and died. I really miss her because she shared my burning hatred for squirrels. NONE WOULD DARE enter my yard with her on patrol. Over time I settled on Welsh Harlequins as the perfect breed for me and now all my ducks are WH.
FREE starter ducks give you a chance to test a breed, hone your skills, and potentially make a little money to offset the feed bill.
