2 of my hens, one a white leghorn and the other an OE, have stopped laying going on about 2+ months now. Both birds made a year old this spring. Neither show any signs of molting. I did pick a "pullet egg" from the OE 2 weeks ago. Could it be they've molted/ still molting with very little feather loss? I'm located in Central Louisiana, could the heat be an issue?
