depends on how you look at it, chicken came first, (this is just to contradict gades, really don't care which) the egg is not a chicken, it is in itself an egg, if by gades therory the egg and hatchling still would not be a chicken. there would have to be at least two of the same species(or mutation) each of the (ie. male & female) opposite gender for that chicken to become a species. this can't happen unless there was one first, so there is a hole, chicken nor egg came first. once the chicken is a species, and not a natural selection of a breed of another chicken, it cannot breed with other species. therefore the chicken had to be created by something, not evolved.
stop there see what responses I get.~
