I would ask for pullets plain and simple.. here's why
This spring I ordered 30 chicks straight run from Purely Poultry, Not a breeder but a hatchery, I figured I'd get about half roo's and wanted about 15 hens, and use the extra roo's as meat, well what I got and what I wanted were two very different things, my 1st order was screwed up my Ancona's, Delwares and BR, were not in there instead they shipped me a bunch of White rocks which took me months to even figure out what I had, so they fixed it with a second order 2 months later, that did finally give me the chicks I ordered, but total I now had 43 chicks instead of 30, and 34 of them were roosters!!. So unless you can raise them till 16 to 18 weeks and butcher all the roosters, your ASKING FOR A HEADACHE.
Not saying it may not be different with a breeder, but chances are at least half of what you order will be roo's, and unless you are set up to deal with roo's it will not be a good thing. I see you can not have roosters in your area, so hiding growing, crowing roosters for 16 weeks seems a bit far fetched as well.
I would keep looking for a breeder who will sell you sexed pullets, you may still get 1 rooster as a mix up but most should be pullets. Or dare I say order from a hatchery, if you do not plan to show your birds, or raise 1 certain breed that you wish to improve upon, I would by hatchery stock, they lay eggs just fine and are beautiful birds though some are not show standard, they do have faults, like wrong comb, wrong feathering, color isn't what its suppose to be, not speckled enough excreta, they do indeed lay very well.
I have 16 pullets, cuz I bought some BSL's and EE's at
TSC to make my original idea of at least 15 hens complete. They lay well all have been laying for a while and most lay everyday, even now in the cold no light conditions of almost winter.
I have 4 speckled sussex, 1 Barred rock, 1 EE, 3 Black sex links, 2 White Rocks, 1 white wyandotte, 1 silver wyandotte,1 Buff Orpington, and 2 Delawares.
I ordered 5 of each of these breeds and mostly got 1 hen 4 roo's ratio. except the SS because 4 were doa and had to be replaced and they could no longer get my Ancona's I took 5 extra SS instead, so out of 11 SS only 4 were hens. and my Wyandottes were 2 of 5 hens, so I have no GLW at all except a gimpy rooster I don't have the heart to kill.
Best of luck with your endeavor's, chickens are wonderful and I love mine, but a headache was all I got with ordering straight run. Kim
