Hi, We have a mixed breed flock of 4 hens and one roo. The girls were all consistent daily layers until about a week ago. We thought they were hiding their eggs, so resorted to keeping them in their 10'x20'run plus coop. We're on day 3 of penning and still no eggs from ANY of them! What gives? And at what point should I be concerned? I just find it odd that they're all withholding... 2 Americauna, 2 bantam mixes. All about 1 year of age. Thanks!
