Fascinating to see the difference in eggs when I put some of ours into the egg carton too. Keep in mind that our chicken are mostly ex-battery hens that once used to produce those cage eggs. They were not considered good and productive enough for the batteries and hence would have been culled if we had not taken them.
We had our lovely cat Kahlua with us for about 12 years, maybe a bit less however after such a long time you lose count – it feels like forever though. You get the idea. After she passed away and we were grieving for some time, we felt the urge to fill the void.
