We just picked up 2 silkie chicks, a black 2 wk old and another 3wk old. We have a white hen we rescued at 9 wks that's now 6 months old. This silkie was given to us as "porcelain" but in looking at the pictures of porcelain chicks online, she looks much too dark! Any help would be great! Also - in others experience, have just 2 chicks done okay at this age or is it common to lose them? Thanks in advance!
