@Junibutt here is a pic of your Orpington's wing color. It really looks solid white to me, which I know it shouldn't, but it does. He has some nice thick legs! So much fun, guessing colors on all these chicks.
ok I found one picture of one of my mauves at 4 weeks old, however none at 2 weeks. I have been told mauve can have different variations in shade due to other factors but this is almost white here. I guess we will check in couple of more weeks
If I got my eggs wrong, then there are several other possibilities. I guess we will have to wait and see for another couple of weeks. I have more eggs hatching on Easter so will have to see if more hatch like this one!
