My Pyncheon is a laying machine. She lays me a teeny tiny little pink egg every single day.

But it takes like 3 of them to make a regular size egg.

My red sexlink is about 3 years old now, and while she hasn't laid all winter, she gave me 4-6 jumbo sized eggs a week last spring through fall, and maybe 2 per month since she started molting in the fall. I had a Delaware pullet who laid daily no matter what, but she was a carrier for mycoplasmosis, so she had to go when we wanted more chickens, so I'm not sure how long that would have kept up. Really I think my bantams are my best layers, their eggs are just really small. I had a bantam sultan who laid a small egg every day, and I have a mixed breed who looks a lot like a Dutch, but a little too big to be pure, who lays about 5-6 eggs a week IF she isn't broody, and she's really broody. lol
I have to agree my EE's are my worst layers. I have 3. One of them I think is mixed with a white egg layer, possibly leghorn (her comb is a mixed single crossed with something else), and she lays beautiful blue eggs sometimes with white spots. She's my best layer of the 3, and she lays maybe 4-5 per week. The other 2, I can't tell their eggs apart and I don't always even get one green egg daily, very rarely do I get 2 green eggs on the same day. They were better in the fall, though. I have a light in my coop, and they're still not laying close to daily. The bantams are in a separate coop with no light, and they're still laying daily.
