If I understand correctly the track of the egg doesn't intersect the track of the waste until just above the vent and that the act of laying is supposed to close off the intestine side. So the egg should only get poopy if it lands in something in the next box. However, I have one hen who always lays poopy eggs. Not just a little speck, a big blob of chicken poop all along the side of the egg. Every single day that she lays. I don't know which hen it is. Its always in the middle nestbox. Other than the poop-smear its a normal, medium-to-largish, mid-brown egg just like the others. And the poop is perfectly normal in appearance. Quite indistinguishable from any other poop in the coop so I don't think she's sick. Any thoughts?
