My OE will be a year old this July, so she's still young. She started out laying just fine, and her two sisters are doing great. This one is very flighty and cautious and has been having egg shell issues. It started 2 months ago when she laid a huge double yolker. Ever since her eggs have been thin shelled but rough like sandpaper, and ranging from white to dark brown with inconsistent coloration. Will she grow out of this, or does she have a defective shell gland? I have also found a few shell less eggs under the roost from her, and her eggs have a lot of meat spots in them. We feed all flock feed and have a large dish of oyster shells in the coop. I see her eating them all the time, so I know she's getting plenty of calcium. Any suggestions?
