Last year my local feed store had some courtnix chicks for sale, so I bought some. They have turned out to be extremely prolific egg layers, and although the birds are slightly smaller than my Jumbo Browns, their eggs are larger. I have no idea what strain they are: they are white with a brown spot on the top of their heads and are a lot fiestier and more active than the Jumbo Browns. I need to replace 5 Jumbo Brown hens who have completely stopped laying. The feed store said they weren't planning to sell any quail chicks this year and didn't seem to know what I was talking about. Any thoughts on the strain/possible source so I can order some hatching eggs from them?
