What are your criteria for setting pullet eggs?

[nataliewt]

Is it a certain size, a certain age or certain amount of time since the onset of laying? My girls (a rainbow layer mix) have been laying for about a month now, and I'm getting the itch to set some eggs. I guess even if it is not optimal there won't be any harm done in setting them, but I am wondering what the "right" answer is.

Thanks!

If they dont seem really small I just set them. Whats the worst thing that could happen? They be infertile.....
