I have 12 hens (3 white leghorns 3 cuckoo marans, 3 EE, and 2 SLW. I had been getting 5-8 eggs a day and was pretty sure 9 were laying. Now I am only getting 2 a day. EVERY DAY. Not one, not three, but two. Its always a white and a blue. I haven't had a brown egg in 2 weeks even though half of my layers are brown layers. its probably because of the lack of daylight hours but im not sure. any ideas?
