Until a couple of days ago I would put a bowl of food and a gallon of water in the duck pen and then walk over to the pond and yell, "Let's go ducks," and the ducks would come running. Well, the ducks have been getting bigger and eating more so I bought a new bowl. The new bowl is white and the old bowl is purple, how was I suppposed to know this would be a major problem. So I did my thing with the new bowl full of food in the pen and the ducks came running and then the lead duck came to a dead stop at the door. The other ducks plowed into the back of each other and there was a big pile up just a few inches from the pen door. Knowing that if they don't go in on the first try I would be spending the next hour chasing ducks I quickly stepped in and shoved everybody in the pen. Instead of diving into the bowl and gobbling up their food they all stood around discussing the matter for about 5 minutes before one brave sole ate from the new bowl. Then it was business as usual and I thought the crisis was over. I was wrong. The next night I used the new bowl and some of the ducks picked up on this from a distance and I only got half in the pen. So I had to chase ducks and everybody got stressed out but I eventually got everybody inside. I decided to leave them in the pen for a couple of days using the old bowl for all feeding. Yesterday I let them out and wasn't able to get a single duck into the pen last night, even with using the old bowl. So they went 48 hours without being feed (plenty of natural food around so they aren't starved). Tonight they didn't want to get near the pen, I think I have made them afraid of it. I reinforced their fear by chasing them around and into the pen, some needed to be grabbed and thrown in the pen but everybody is locked up and safe. My plan is to get 50' of poultry wire and make a run for them and re-train them to go back into the pen at night. They aren't going to be happy when they realize they can't get to the pond and I am sure the turkeys are going to be teasing them. Anybody have any suggestions on how to reverse this behavior?
