Thank you to everyone. I am glad my girls are fine. They are pretty slow to do everything it seems.
They have a little pond and for the 1st 5.5 months of their existence they avoided it like the plague. I tried chasing them in the water, but they acted like it was hot lava. They wanted no part of it. I had to set each of them up with a dishpan of water to sit in. About 2 weeks ago I came out and both were in the pond. No clue why the water is suddenly ok, but they definitely think it is. They are in the pond all day long until I put them away at night. Maybe laying eggs will be a similar thing. I will come out one day and there it will be - a magical duck egg. I have heard duck eggs are AWESOME for baking, so I can't wait!
