Which is the best way of preparing eggshells? I dry mine in the sun for about a week then crumble them for my finches to eat. Are there any other ways of cleaning them?

Bake them in the oven

Yes, but for how long and what temperature?

Zap in microwave for 2 minutes

I prefer to Bake in oven. About 180- 200 degrees 20 minutes. You will tell if they are over done they look burnt. I would not bother to fire up the oven for less then a dozen eggs.

I wash them straight away so all the white is removed from the shell ie the clear fluid which turns white when you cook it. I leave them to dry out on the sink, once dry I microwave for 2-3 min depending on how powerful the microwave is.

I do the same Shnapper, it's quickest and easiest way though it freaks me out when start crackling and popping in the microwave. Craig

I do the same as Craig and Snapper but be very careful with the power of your microwave as i had to purchased a new one , i burnt the egg shells ,the stink was unbelievable and the look on the wife was so bit by bit till you get it right,garyh

boil egg for 10minutes, eat egg give shell to bird.

Out of an abundance of caution, I wait until I have maybe a dozen shells which I bake in the oven at 180 deg C for 30 minutes. I have been advised that the calcium remains intact through the process. I then smash them in a coffee grinder. Seems to work OK. I have tried putting out half-shells but my snappers ignore them, preferring the ground-up shells.
