We just found our first eggs this week, yoohoo! We have 3 hens all a little over 5 months--either Americana or EE's. Based on her behavior of always laying down, we are pretty sure only one hen is laying one egg/day right now. Couple questions: the eggs are really small and we want to know will they get bigger with age of hens? Also, they are brownish green, does this tell us which species they are? Thanks
