well i have 25 silvered laced wyandotte chicks that i can't really tell apart. will fingernail polish on a toe hurt them? or maybe food coloring on a toe? i can pretty much give each a "toe code" to tell each of them apart with only 2 toes colored if it won't hurt them. also i have 2 basic types of chicks. some have white neck, breast, and wings. they tend to be more aggressive and will rush each other and see who is taller. i'm guessing these are the roos. the others are all duller colored. they seem less aggressive. i haven't seen them do the hight contest thing either. i'm guessing these are the hens. if anyone knows if i'm just being self deluding let me know. also should i post this question in the what am i forum?
