I have five adult chickens only one of which lays blue eggs. She went broody and had a hatch 4 weeks ago. I also have a group of girls that are 21 weeks old some of which should be EE. Yesterday I got a little blue egg. About 2/3 the size that my EE was laying before she stopped. So the question is, do hens start back with smaller eggs after coming back from being broody, or is it more likely that the next generation is coming of age?
