My older runner duck has been laying soft shelled eggs at the same time every afternoon for several weeks.  I pulverized a calcium citrate pill and tried to give it to her via treats, but she once she realized the CC was on there, she wouldn't touch them.  Then I tried to syringe watered down CC in her mouth, but she never swallowed.  Does anyone know of any other way to get Calcium in her?  Also, could this be a reproductive issue?  I noticed after she lays the egg, she seems out of it and her pelvic region pulsates a bit, like she's sore down there.
I do see her eating oyster shell, although I don't see her shoveling it in. It's usually just a nibble.
