I picked up 22 assorted laying hens from a friend. I couldn't pass them up as they were free.
Some red sex links, white Plymouth rocks, silver laced Wyandottes, and what looks to be white leghorns, (But they all lay varying colors of brown eggs. And I didn't think leghorns layed brown eggs.) But I digress, the leghorn look alikes (Maybe leghorns!) lay 110-125 gram eggs everyday. (Two weeks and has not missed a day, not sure what he was feeding them, but these eggs put store bought jumbo eggs to shame, in fact the egg carton for jumbo eggs will not close with these eggs..) I was talking to my friend about this, and he said they do that pretty much everyday, and once in awhile will lay two eggs a day. He showed me a picture he had on his phone of an egg one of them layed, that was sitting on top of the egg pocket of an egg carton. he claimed it weighed 204 grams, just over 7 ounces and had four yokes. (Don't know if it were true, but the egg was bigger then any goose egg I have ever seen, and these chickens are 3-3 1/2 birds, very small.)
I now have 45 layers, and have a light that comes on at 3:00AM so they have 15-16 hours of light everyday, When I get home from works at 5:00AM there is always at least 20-25 fresh warm eggs, then when I get up at about noon, I gather them again, and get about 20 or so more, my younger pullets are still laying a medium to large egg, (55-80 grams, not sure why I weigh every egg, but I do.) so I know the new birds are the only ones laying those monsters, beside, the huge eggs started arriving when I got the new chickens.
