duck layed a strange egg

[Bird Worrier]

Tonight I found an egg in the duck's pool. Interesting place to lay an egg. Then to see that it has no shell. Any reactions?

Do you give them any oyster shell?

It could be lack of calcium. X2 SniperGoose. Oyster shell has high calcium, so if you don't give them it, I would start.

One of my older ducks layed an egg in the pool but only one time and it had a shell. I had a problem with shellless eggs too. I then started putting oyster shells out in a bowl but they'd knock it over and just make a mess so I took a clear 24 oz soda bottle and cut it off 1/2 way and drilled some holes in the bottom of it for drainage and wired it (using a couple more drilled holes at the top) right to my fence so the girls can eat the oyster shells when they want and as much as they need. I believe they instinctivly know how much to eat. It works great for them and me. Simple and free.
