Today has been the best egg day I've ever had! 24 eggs so far today....of course, the fact that I found a hidden nest with 15 eggs in it under my shed contributed. Apparently, a few more of my ameraucanas are laying now than I thought and they all followed Sky under the shed. I'm not sure what her issue is but she insists on laying anywhere but where she's supposed to. I swear, she actively seeks out anywhere other than nest boxes to lay.
A man's opinion, some girls are just shy.....maybe you could pen her for a bit to force the nesting box, once she's there your gold..(also could be a broody thing going on an the girl is quitting..)
