I have 6 EE hens at 25 weeks old. On 9/28/08 we got our very first egg, and we have only been getting one egg every day since (missing a few days here and there). Why aren't the others laying? We have actually witnessed which hen is laying. The others go in and out of the nesting boxes, but don't sit for any length. IS THIS NORMAL? WHEN SHOULD THE OTHER GIRLS START LAYING? I'm starting to get impatient.
