So my duck has been laying great for a few months now. Up until about three weeks ago, they had nice, strong shells. Now suddenly they're thin and breaking really easily. As soon as I noticed, I added crushed chicken/duck egg shells. They seemed to get stronger for a week. Now we're back to paper thin. I feed her Layer Feed. Do you think I should quit the egg shells, and switch to oyster shells? Anything else I should be doing?
The other weird thing is that at least once a week, she'll lay two eggs in one day.Leave it to me to get a bizarre duck, lol. I'm positive that I have a hen and a drake. He has the tail curls and is a little meanie, too. He hasn't managed to bite me yet, but that doesn't stop him from trying/pretending. It's kind of funny. He'll start to run at me, get to about a foot away, and then runs and hides.
