We purchased our first ducklings in Dec. They are now 8 wks old. This past weekend we herded them to our stock tank that is about 100 yards away from where they are now in our back yard. The herding went well but they only puddled around in about 1 ft deep water for about 5 mins and then headed straight back to our yard. I was shocked and disappointed. I took them back again later in the day and the same thing happened. Our plan was to have 'weekend trips' to the tank and then eventually move them entirely out of the backyard and to the tank. They will have fenced in protection into the tank but they will always have open area to come and go. Any suggestions on how to transition them to a new 'home' base? Thank you.
