How is your Sapphire Gem doing? Mine are 23 weeks old as of Wednesday, and I have seen several double yolk eggs (HUGE eggs). However I have one that is laying soft shell and sometimes shell less. Her name is Luna and she is a flock favorite.
At first I wasn't quite sure who was laying the soft and no shell eggs, as they were being laid at night and found under the roost below 2 of my Sapphires. I added an extra oyster shell feeder in my run, because I figured whoever it was wasn't paying attention to the first one.
I'm pretty sure she was laying twice, once with the soft shell as well as a hard shell because I was finding 7 hard shell eggs a day from all 7 of my sex linked chickens. The last 3 days I have been short an egg.
Last night I brought Our Sapphire named Luna in because I noticed she was acting off as if she was needing to lay, but couldn't. After they went into the coop last night I found her below the roost (which is odd for her because she is at the top of the pecking order and ALWAYS on the top roost) I brought her inside and fed her some yogurt for the extra calcium and probiotic. She then pooped what looked like egg white mixed into it, and dropped a single yolk with no shell at all. I'm not sure what to do.
This morning she seemed perked back up, the first to greet me when I was letting the girls out of the run. My Sapphires began laying at 18 weeks old.
