Well I've done it. I ordered 15 pullets from Hoovers, all are Chzech hybrid egg layers. Midnight majesty "marans", Sapphire gem, and Calico princess (5 each). I've had the sapphire before, and the midnight majesty appear to be the chzech DS109 dominant black, which are used in africa, and the calico princess (D459 dominant red barred) also are used in pakistan and bangladesh, so those are the least heat tolerant of the three. I'm hoping to sell 3 of each of those breeds, ending up with two of each to supplement my four andalusians (who are doing great in the heat so far but barely holding to their 280 eggs/year each). I'm not completely insane, I did measure an area inside my existing fully secured run and eyeballed the area between the run and my house. Hatch date is 9/15 so I'll have them 9/17. According to the weather underground I should have enough cooling by then to only have them in the bathtub a short while, which I'd do anyway since they're mail order.
Good luck with them when you get them! If those Maran's lay dark enough egg's, you shouldn'have any problem in finding a buyer for your extra's.
I have been debating over here if I want to get a Blue Double Laced Barnevelder rooster over here for starting my second pen going with or not. Then I would have a matching roo for my 2 hen's like that. Right now those 2 young hen's are in with my Naked Neck's.
