I had one hatch that looked similar to that one a few weeks ago. I think it is a SLW and white rock cross, or it could be either of those with a columbian rock! There are only 4 breeds in that pen, and it sure ain't a RIR!!
Here's a pic just after it hatched...
And here's one at about 2 or 3 weeks, I think.
It's the 2nd from the front on the left!
