I have a RIR hen who is the only one of all my gals thats laying. This is her first year so I guess shes still a pullet? Anyhow, shes been laying for a couple months and I have noticed that her eggs are usually different sizes and shapes which I know will be normal since she just started laying. What is odd is that they change colors too, they are sometimes a dark brown for a week or so, then they got lighter, and now today she layed a pink colored egg! She free ranges all day everyday, and has had the same feed available, so what could be the reason for the changing colors and lightening of her eggs? ETA: Its definetely the same hen laying the eggs, shes the only one and i see her in the box all the time and saw her today.
