I have an EE that lays green/blue, two marans that lay brown a Legbar that laid her first baby blue today and a 10mo old Legbar that lays olive eggs we brought in 6 days ago and has laid everyday since. Today one maran went in and laid, then then both legbars. However the egg my husband found in the coop was cracked open, yolk gone and double soft shells (will attach photos), however both legbars laid shortly later perfectly fine eggs as well as the other marans. We cannot figure out who laid this soft shelled egg because it's brown inside!! Any ideas!? Note the soft jelly looking shell was inside of the other shell.
