1 doz
I intended to give them to my neighbor who loves my chickens and has never complained about them coming to her yard, and doesn't even seem to mind the rooster crowing.
So I knocked on her door and gave them to her hubby who answered the door.
A few minutes later she came over and gave me a dollar and said she would buy any extra eggs whenever I had them.
With only 3 layers I'm not exactly trying to sell a ton of eggs, but when I was sick they piled up a bit and I figured I'd share the wealth.
