I have had five eggs total over the last two weeks---alot of you here shared my glee--anyhoo--today there was one mushy, no shell, perfectly perfect in the inside egg. I am feeding them calcium but is this just a fluke? One of the previous 5 had a thin shell that had some translucency to it--is she just having trouble getting it together? the other eggs (I think from a different pullet) are gorgeous and double yolkers with strong shells.......
