I have a couple of questions. I placed ten silkie and/or frizzle eggs in my incubator. I candled them today (day 3). 5 have what are clearly a red ring that doesn't move as I rotate the egg slowly while candling. (As if it is stuck to the side of the egg) 3 that appear to be fertile but very porous looking. 1 has the spidering but does have a light red ring as well but it moves with the yolk. 2 appear to not be devolping at all. I guess I would like a little more detail about blood rings. That means they began devloping an then stopped? The eggs with the red rings that didn't seem to move as I turned the eggs....should I go ahead and toss them now? What about the one that seemed to be spidering but the ring moved as I turned the egg? Also, most all of these eggs seemed to be porous. What would cause that? They have oyster shell and a healthy diet. Thank you in advance for your advice.
