Looking for some help IDing these 3. The rooster would be a RIR, however the mother could be either a RIR (1 in the flock) or production Red (7 in the flock)
This one is about 3.5 months. Coloring is close to the production Red hens in the flock.
Same age as the one above, but I'd lean toward cockerel.
This one is about 2.5 months. Next to it is a Black Sex Link, which were much easier to ID...
