My first Broody hen has been sitting for a month or so. I finally put 3 eggs under her 3 days ago.She has kept them hot and hasnt left for longer than a brief moment once a day. I brought them in and candled them tonight....2 had big dark areas(bigger than a yolk) that moved when i turned the egg. The 3rd looked mostly clear with a pea sized dark area. I didnt see any veins, but my eggs are dark brown so it was hard to tell. I will check them again in a few days. Im just curious if I should be seeing anything in particular at this point?
