I have a flock of 10.eleven week old chicks.one is a rooster.yesterday he cornered a pullet in the run and pecked her really bad. he would not let up.i ran in the run and the little pullet was able to escape.i cornered him and picked him up.and i smacked him and fussed at him.(i know that sounds stupid on my part)but i was so mad at him.i come closed to wringing his neck.is that normal to be so mean when they are establishing their pecking order.also he smells really bad like chicken poo.i treated him for cocci a month ago and he smelled bad than.normal ? or not.the rest of the flock does not have that smell. thanks in advance.
