They have some attitudes, that's for sure! I hold the one that keeps doing that above the chicks, for about 30 seconds. Watch it after I set it down, and if it does it again, hold it again. Kinda like "embarrassing or shaming" them. Seems to work most of the time. Even when it(they) aren't...
All sexes will do the fighting thing. Where they stretch their necks out, and puff up their chest. ;) But I am thinking the fifth one is a rooster. The Silikes are too early to tell.
