Looking for advice on a nesting guinea. She has been on her nest since beginning of July. I put some additional eggs under her from a guinea that was killed. I have candled them and some are mostly dark with a little lighter area at the top while others are clear. Guessing the clear ones aren't any good. Should I give her more time? Will soon be 6 weeks since she started sitting on her nest. She is very determined to stick with it!
