I got two of these in a rainbow layer mix. They are 12 weeks old and much smaller than the other birds in the mix. They are also really fiesty. I recently moved the cage from my garage to the big girl coop, and this little one tries to escape and run with the big girls every time I open the door. She dosen't seem to be intimidated at all. Their tails are quite long for their size too. Please help me identify the breed. Sorry I couldn't get better pictures. I hope these are good enough.
