I didn't start this without researching some, and I've read what I can about breeds that lay large brown eggs. However, I've always trusted word of mouth more than scholarly or wikipedia type info. I've been raising chickens about 6 years. Last year I bought a cheap Hovabator to hatch some eggs, and enjoyed it. At that time, I wanted some Black Copper Marans, as I was after the dark egg layers. I had good luck with them. This year, I think I want to go after Jumbo layers. Like always, I like the brown eggs. I haven't had a double yolk layer for a couple years. We have coyote and hawk problems. I had a Rhode Island hen that laid some from time to time, but lost her. Have some red sex links, black sex links, and cuckoo maran hens also. The sex links are pretty darn good layers, but for variety, I'm thinking of buying some Welsummer hatching eggs. Never had them. What do you experts recommend for jumbo brown layers? I just like to explore.
