I know mostly everyone gets excited when they see that one of their hens laid their first egg and some may want to save it and keep it forever.
One of my pullets just laid her first egg and I'm tempted at preserving the shell, just to keep it as a memory as crazy as that may sound lol I was...
She hatched! Unassisted. I was surprised she didn't get shrink wrapped since I had taken her out of the incubator twice and people say that they'll get shrink wrapped when you do that.
