We started getting our first egg on Saturday. Which I thought was kind of early since it is February (middle of winter in IL). I was just wondering what the first few eggs look like (color/size). We have 5 red sex link girls and 5 plymouth rock girls. Do either of those lay big brown eggs or do they stay the size of white eggs that you buy at the store? Does the color of the eggs vary between light and dark brown? Also, what age do plymouth rocks usually start to lay? I'm pretty sure that the eggs we are getting are coming from 1-2 of our red sex links.
