I have 3 black Cayuga hens and 1 black Cayuga drake. 1 hen is a year and a half and the rest are just over 6 months old. I still haven't had any eggs from my 2 younger girls. When do they start laying? I didn't pay much attention as to when my older girl started laying. Next question that sort of ties in to the first. I buried a horse tank, (one of the big round ones) in my back yard out by the duck pen. When we first put it in the ducks would run straight to it every day and splash, play, dive etc forever. We have about 7 fairly big gold fish in it (5-6 inches long) and I think they spent most of their time trying to catch the fish. They played in it for 3-4 months and one day they didn't run straight to it when they were let out in the morning. They haven't been in it in a month or two. You can't make them get in the water. I don't know what changed. Any suggestions? Since they won't get in their huge pool... we dug out a hole in their run and fill it up with water. They "swim" around in that all day or in a small round kiddie pool they have in the run, but you can't make them get in the big tank in the ground. The drake tries to cover the girls in the small bodies of water but I don't think he is making any progress cause they aren't deep enough. How deep of water do they need? My older girl... well she won't get in the water at all. Period... she thinks she is a chicken and sticks close to the rooster regardless of where the other ducks go. It is just one thing after another with them. I've never had ducks before so I thought I would come here and get the scoop.
