I ordered 15 BLRW in a total order of 25 chicks from McM last Spring. 5 were DOA, 3 more died within 24 hrs (53%). McM was good about it and refunded my card. It did take 3 days for arrival on Priority Mail. I felt that stressed them more - but of the other 10 chicks in other breeds, only 1 didn't make it (10%). So overall, it seems the BLRW were more fragile.
OK...so of the 7 that lived, all survived to maturity. ALL of them were also Splash, 3 pullets and 5 roos. (All splash was disappointing to me.)
I kept the 3 pullets and 2 of the roos. Here's a pic showing them, except for the spare roo:
Regarding their color quality, one of the pullets (A) is a good mahogany red. The others are too gold. The roo's color is fairly decent, a little too gold in the hackles but good for hatchery stock.
I've since gotten some very nice blue pullets from a breeder. I'm going to breed those and the one better pullet from the McM stock. Then I'll cull hard to start improving the line - and will be buying hatching eggs from another breeder this season to add/improve.
Bottom line - I won't order anymore BLRW from McM.
Hope this is helpful.
