Alalele- you could have a red-sex link. My ISA Browns feathered out a "creamy" white, then the reddish feathers came in a little later. Other options could be White Rock. Feed stores usually don't order in a big variety and the sex links are popular.
I'll have to go look at my Buff Orp babies in the brooder this morning to chime in. It's been a long time since I had Buff Orp chicks and I just remember the pinky baby legs they all had. I'm moving slowly-bad headache last night necessitating lots of meds, so I'm like molasses today. I'll get back to you soon here.
I have a mystery pullet that looks just like that! So far pure white feathers...I have another that looks to be a splash something. I'll try to post pics soon.
I have brand new buff orp babies that hatched out with whitish pink legs. The only chicks Ive had with yellow legs like those are rocks.
I found this on the Orpington site that describes the standard:
Serious defects
Side spikes on comb. White in ear-lobes. Feathers or fluff on the shanks or feet. Long legs. Any deformity. Yellowskin or yellow on the shanks or feet of any variety. Any yellow or sappiness in the white.
