My BO started laying about 3 weeks ago. They were perfect little light brown pullet eggs. The we're progressively getting a hair bigger and staying the same light brown color. Her last four eggs have been a different story. Colorwise they went from light brown to pink to cream to white. Sizewise they got smaller, with today's being smaller than her first. Is this a normal pullet thing? Should I be worried? Just so you know, a cursory exam says she has no mites or fleas. She does not appear to be having a juvenile molt. She has been acting normally (except she was in the nest box quite a while laying today's egg and got agitated when flock mates tried to go in with her) and eating regularly.
