You can see from my profile the breeds of chickens I have. I have one 1.5 year old BR, the others are about 9 months old. All have been laying consistantly since Aug/Sep. Although production droppped significantly (from an avg of 8/day to 2/day) just after our first cold spell, the number of eggs returned to almost normal after a short spell. We had moderate temps and all was well until this past week. We had another several day cold spell. Egg production is down to just one or two a day for 11 layers. Here's the wierd and unexplainable. All of my birds lay varying degrees of brown eggs. Except the two from today are WHITE, well almost white. Has anyone experienced this? Reasons?
