I have 6 chicks.ever since they had begun free ranging little "Clicks" were formed,but this was 4 week old 5 week olds. Here we are at 8 and a half week old and this chick has been very distant with other five,occasionally he will stay with them now that they stick as one whole flock (Sometimes.)He roosts alone,and maybe its just he isn't committed to flocking (He spends more time around me then them I think.)I'm almost positive he is little cockerel (I named em Brutis.)maybe he is committed to watching over them (although i'm not sure he does.But would you have any idea WHY he is standing alone all the time?
