Actually, I'm inclined to think that baby is a BR/SLW with my single-combed Wyandotte, Lorelei, as his/her mother. I suppose time will tell as the baby develops.
The Blue Orp/Buff Brahma babies are doing great. The blue one has lots of leg feathering and I'm positive is a cockerel because he's already crowed. He's going to be a very strikingly handsome boy for someone some day since I really have no place for him here. The chocolatey-black Orp/Brahma with sparser leg feathering seems to me to be a pullet; still, it's a little early to tell 100%. They are both very pretty babies. I had pics of the probable pullet, but they were way too grainy and dark to keep.
