I have a year-old SLW that I don't think is laying. I know I read somewhere on this site that one way to tell is to insert a finger (with a glove on!) inside the vent and that one should be able to feel the egg forming. The problem is that now, I can't find the post where I read this! Has anyone else heard of this or even tried it? I did try it this morning and felt nothing, but I would hate to cull her for no reason.
