I have Tulip an Easter egger (just over 1 year old). She eats scratch and peck grower feed. There are 12 weekers with her which she’s amazing with. I started fermenting her feed and she laid one shell less egg and zilch since. She has oyster shells free choice. She seems fine otherwise. Happy as can be and pooping fine. I did give her a calcium tablet. That was an ordeal and not wanting to do that again. I started fermenting her feed and not sure if that changed anything but not one egg since the shell less egg. She also gets crushed egg shells every evening. I am at a loss of what else to do!
