When my younger flock goes to roost at night, one of my 6 week old chicks "Cash" roost right next to his dad "Impy". Impy is fine with it. However, the last few days the two other chicks, TJ and Rowdy, try to roost next to Impy and Impy has a big ol' hissy fit. He knocks them down and they end up roosting somewhere else. Isn't it weird that he would allow another cockerel to sleep next to him, but not the other two? One of these days I'm going to figure out roosters!
