I haven't seen a consistent smaller egg size in the females that were left with males. Although I have seen more eggs with odd shapes indicating stress that came from the females that were left with the males. And have had some start laying a lot earlier when they were with males the whole time.Thanks. Also, if you don't mind, does separating the sexes also help the pullets. Seems like I have heard that there is an optimum way for pullets to enter their first laying period. And if there are too many cockerels around they will start to lay too early before they reach the preferred body weight, resulting in smaller eggs than normal, even for pullet eggs. Or, maybe the better way to phrase it is they start laying when they are suppose to, but because of all of the running around ( as you mentioned above) they are below weight. Just read NanaKat's post. I think we answered the question re: the pullets.
Thanks again,

Had read about separating the genders but didn't think it would make that big of a size difference. Did it this time mostly to try to stop the cockerel fights. It was a big eye opener this time around to have such a size difference AND not have frequent fights between the males. Everyone is much calmer. It is definitely the way I want to keep going from now on. The difference has really been more noticeable than I thought it would be.
