Today I went out side to check on my 4 three month old baby silkies (I let them free range in my city lot) and one of my silkies started to attack one of my other silkies and they started to peck, kick, & jump. Three were in the the fight and the only one left was the smallest one that was eating. for sure the one that starten the fight was a boy cause it has the biggest comb and the other ones in the fight might be boys cause tiny combs but the one that was not fighting did not have a comb. the question is: were they fiting cause they're cockerals or were they fighting because of canibalism and even if they did fight if they were cockerals aren't they yong to fight? is this normal?
