Eggs, no shell, Calcium Issues?

[casportpony]

Feeding greens like kale and collard greens is also a good source of calcium. Spinach, while high in calcium, also contains something that inhibits calcium uptake. I forget the name... Will look for it.

Spinach is very high in oxylates and iron, so that might be what you're thinking about. Some people say it's fine in small quantities, but I don't ever give it to our ducks. I always tend toward caution, so my feeling is why give them something in any amount if it comes with warnings. There are so many great things they can eat without problems, so I completely avoid anything that is potentially harmful. As much as I love spinach, I've almost stopped eating it myself because of the potential health consequences.

Oxylates, that's what I was trying to remember! Somewhere I have a good article about it.
