I hatched 3 pekins in the middle of April and raised them with my chickens. They had a small pool and never were afraid of the water. I got 2 more that were about 6 weeks old when I got them around mid June so they weren't alot younger than my original ones. Two weeks ago we fenced in an area on the lake. 1/2 on land 1/2 on water. At night they locked in a secure pen. When I first put them in their lake pen, they LOVED the water. Splashing, swimming, diving, all of the things that ducks are supposed to do. About 4 days later, they wouldn't get in that lake for anything. I threw them in and they scrambled as fast as they could back on shore. So what do you think happened? Do you think snapping turtles could have gotten after them? There are definately snappers in the lake. We are working on removing some of them now. Any other suggestions. I am trying to get as many turtles out of the lake as possible this week since I will be getting 3 new ducks this weekend and hopefully, they won't be afraid of the water and my current ducks will follow suit and get back in the lake!
