How do you know when a pullet's eggs are mature enough to incubate? I have an 8 1/2 old bantam Araucana pullet that began laying late February (at 6 months of age). Her eggs were a consistent size of 1.31 oz. The past 2 weeks her eggs have been consistent at 1.34 oz. I'm getting ready to set a batch of eggs Wednesday; should I throw in a few bantam eggs or give her more time to mature?
