Hi, new to BYC and have 6 chicks that were hatched by my daughter's kindergarten class.(12 weeks old) The are from a local farm with several breeds (all cross breeds:not sure how that works). 4 I believe are Cochins (feathered feet) and one appears to be a black Easter egger (funky sideburns) and one a silver colored smooth legged gal (?). Based on comb size and color, I am pretty confident that 2 are roosters, and 3 are hens, but the final one seems trickier. I have uploaded some pics of each.(1R 2R 3? 4H5H6H) Any help would be awesome.
