when I crack the eggs, the membrane just beneath the shell is super firm and I have to punch through it with my thumb. I feed her laying crumble, they have a mineral block and free range at least 3 days a week. The eggs are very bland with bright yellow yolks and a bit of cloudiness in the white part. Could someone please tell me what I am doing wrong, or if their is something else going on. BTW she's only been laying for three weeks.. maybe that has something to do with it???
