Sorry! I'm gonna go with Mahonri hatching 54 chicks.
Ameraucana, Orpington, Icelandic.
But... what if he gets Ameraucana, Ameraucana, Orpington, and Icelandic? If Ameraucana is the first breed to hatch and Orpington is the second, does it matter how many of the first breed hatch before the second breed gets here? If one dies (God Forbid!) in a day or so after hatch, does it still count toward the hatch rate? What if that one was one of the first three, does it alter the breed order?
And I had to do some back reading to find the list of breeds set, so I was catching up a bit... for The Warden, what an awful situation to be stuck with.
I agree, shoot the dogs if you have to. Or trap them and turn them over to a shelter/the pound/someone on Craigslist if they're on your property and you're not too eager to shoot. They can keep getting more animals to raise irresponsibly, and you can keep rewarding them for their irresponsibility. Neighbors have no right to terrorize!
And finally... I love the cardboard box brooder! If you need more room after New Years, you could easily just add it on!
