Pekin duck owners - scenario: I have 5 chickens & 1 Pekin female. They were raised together. The duck thinks she's a chicken. She's about 21/2 yrs old. We have a pond and she won't go in the pond .....because she thinks she's a chicken! I am doubling my chicken flock this year to 10. Went to farm store to get my biddies and there they were ......biddy little Perkins! ??? - can I add a duck to this situation? Is there anyway to sex that little biddy little duckling?? And will adding a duck give my present duck a sense of "duckness" - will 2 ducks go 'swimming' where 1 duck won't????? The present flock sleep together, eat together - and actually in the pecking order of things, the duck leads the pack Help me! Just tell me it won't workso I don't go home with duckling today. (that darn duck is our favorite!) Thanks in advance!
