I am really curious about what is going on! Twice now I have found two eggs at once broken on the ground. Both are very pale brown with extremely thin shells. My RIR and BO both have laid each day I found the other two and their eggs are strong and dark. What is more likely that two such young, 15 week old BR's are laying immature eggs (although they are normal, small size and look good inside, it's just the shell) or that one 22 week old is starting to lay and lets go of two at a time?? Seriously those are the only scenarios. It also seems it happens overnight and that they just drop them from the perch. I check every night at sundown and everymorning at sunrise, so I am not missing much. All are eating the oyster shells in the run. The 22 week old that I suspect, possibly (except for 2 eggs at once each time) eats alot of the treats, so I suppose she's not getting enough protein. She's huge, but I've also read that LB's mature fairly late. Anyone have any ideas? It's a true egg mystery!
