Zig, Just remember if you have a breed engineered to lay a lot of eggs it will burn out really quick. Be prepared to replace them all within two years. I beg to differ a little on the laying aspect of the birds. My English Orpingtons and my black brahmas crank out eggs like crazy that are really large as well. The American bred orpingtons were lousy layers though for sure.
Our Sutherlands sometimes carries the Allied pet bowl and Bluestem farm and ranch in Emporia carry it as well. The DIY store carries them (they are an offspring of Sutherlands). I'm sure I've seen them elsewhere but not at Orcheln's.
I would agree about the English orps at least at this point. my 33 week olds (4 of them) are laying 2-3 eggs a day, and I think one of the 23 wk olds has started laying. I'm not sure but there are some small eggs in there that don't look familiar. And this is January.
The Bredas are really laying well, too considering the season. I'm loving the colors of eggs.
