Hi, my first batch of chicks ever - 15 RIR pullets, doing well, turned 2 weeks old yesterday. On arrival, all were pale yellow with red stripes on back edges of wings - except one, who was dark red all over. Now that their first feathers are coming in, the dark red one shows black bands on her wing feathers. Is this usual, or is she some other breed? Or a rooster maybe? Or what? I ordered through my local Agway store, so I don't know where the chicks came from... Thanks for any info anyone can give.
