I have 11 RIRs (production reds mainly) that were hatched earlier last spring, so they're not quite a year old yet. We've been getting eggs from the since September last year (average of 9 with a range of 6-11 each day)--all large and brown to light brown. During the past few weeks, we have noticed the occasional white egg each day (about 4 in the past week). It really sticks out compared to the other ones, but is about the same size as the rest. Do we have a RIR laying an occasional white egg??? Has anyone else every ran into this with RIRs or production reds where they may occasionally break stride and go white? We're in Michigan and it is wintertime with cold temps--is it something from the temperatures?
