We hatched 2 Barred Rock babies from hatchery eggs and 1 possible mixed Barred Rock and Rhode Island Red mix from our neighbor. The mixed egg was the only one left when his chickens were attacked and killed, so he gave it to us to raise. We need to know if the 3 birds are roosters or hens. Any advice? The mixed baby, Little Bit, is in the top photo, then Gracie and Stripes, our Barred Rock babies. We also have a Golden Laced Wyandotte hen, two white Silkie hens, a white Silkie roo, a black Silkie roo and 2 Black Astraulorp hens. They are all about 3-4 weeks old now.
