i have a mixed flock of 12 hens, which includes 3 ee's. one of the ee's lays a green egg, another lays a pinkish egg...the third didn't start laying until she was about 1 yr old. she started laying light blue eggs for about 4 weeks or so and then stopped laying...i never see her in the nesting box, so i assumed she is just a poor layer. but the past several days we have collected 11-12 eggs from our girls, which should mean 1 from each. but we have only found 1 green egg, no blue?! so has my lazy layer switched to laying brown eggs? is that even possible?...i should add, my family & i collect eggs frequently and it would be almost impossible for us to miss an egg from the previous day. any thoughts?
