the beautiful light brown ones look like easter eggers to me (meaning they will lay all different color eggs from pink to lavender to blue), the striped looked like barred rock (light brown eggs) or marans (dark chocolate brown eggs) and the red looks like a rhode island red(brown eggs). They will be forever greatful to you!!! They look to be in good shapre despite the living conditons you described, I would bulk up their protein right now by scrambling eggs and feeding that to them, plus scraps of any sort, good luck and welcome to BYC!
