We have 10 Isa Brown hens that are almost a year old and we've been getting 9-10 eggs per day. We have 12 nesting boxes in the coop. A couple of times over the past two weeks, my DH has found that a hen has laid her egg outside the coop in the chicken run. Yesterday, he found two eggs out there. The weather has been 50's and rainy and now back into the 20's (darn Indiana springs!). Anyone have any ideas why we've suddenly started to find an egg or two outside? Thanks!!
