I'm always reading posts where people will know which of their hens are laying, and which eggs are theirs. I have never been able to figure this out, save for the handful of occasions where I've been right there when one of my girls lays. I have 3 RIR's and 3 Br's, they all lay brown eggs. I have a couple of hens that I'm concerned about, and I would like to try and figure out if they ever lay any eggs anymore. Is there some type of technique? It's not as if I can sit out there all day and observe each and every one of them. I thought perhaps if I dabbed their little heinys with food coloring or something each morning, it might 'mark' the eggs as they come out. But this seems silly and impractible. I'm concerned about Margaret in particular, as she has a bare swollen abdomen, and will just sit in the boxes throughout the day. But I don't think she's laying. Any suggestions?
