I have four eggs in the incubator right now, two silkie and two EE. First time so not completely sure what I'm seeing. Im thinking the first photo is a blood ring? The second is dark green and difficult to see through but just has a large shadow, the third seems porous? All of the lighter green eggs seem to look like that under the light and they are from the same hen is she just laying faulty eggs?. I didn't take a photo of the last egg but it has clear veins and movement!
