By being a chicken nerd and spending too much time in the coop! When you go to check for eggs and someone is on the nest, wait and watch until they lay. Then you can examine the shape of the egg or other "quirks" in their eggs that you can identify.
My light brahma lays an egg with a very pointy top
My EE is my only green layer, so that's easy
My buttercup is my only white layer, so that's easy
My BR lays a very large, more oval egg
My RIR lays an egg with tiny white speckles
1 welsummer lays a slightly lighter egg with speckles, the other lays darker eggs sometimes speckled sometimes not.
Ok, I am a blonde (not really, but I pretend to be
)Can someone PLEASE give a good description/explanation so I can get a visual and know what I am doing is safe and right. I have searched and searched this topic but I don't quite understand what to use, how much to use, etc... I have 13 older hens and only getting between 2 and 6 eggs a day, I would love to know which ones to cull.
