I have four blue (?) orpingtons that are around 21 and 19 weeks. The two oldest are the darkest, they are a dark, dark blue. The two youngest are much lighter, are they splash? I fear that I have all roos, considering their tail feathers all hang down the sides. The seller said there were at least two definite pullets, but I don't know which ones that was supposed to be. Noone is crowing here, besides my little mix roo. Start making noise boys, it will be helpful! Lots of pictures coming up, sorry about the quality.
