I've got only good things to say about both Delawares and Austrolorpes. We've had wonderful results with a cross between DE x RIR - they embody the best of both breeds: the cockerels get big (and delicious) and the hens lay well. And they are mellow. The funny thing is, before Pringle wrote to suggest the Austrolorpe, I was just toying with the idea of breeding Austrolorpe into our DE x RIR crosses, to create the Super Mongrel.
