I have 14 hens born this spring. Many have started to lay within the last week. My question is based on egg color can I determine who is laying? I have two EE's, so that's easy. I am getting 1-2 med. greens eggs a day. I was getting a nice dark brown large from my RIR, but appears to have gotten lighter over the last few days. Does that happen? The rest of the eggs I am getting are light-pale brown, also large. Are those coming from my BO's or BR's? My other hens are California Whites. I am getting 1 small white egg a day. Any info. would be appreciated! Thank you!
