I have just under 20 3-week-old bantams, including Japanese, D'Uccles, Cochins, Silkies and one little blue probably OEGB (came as an 'assorted bantam'). The OEGB has recently been named JB- for Jail Bird, as we've had to separate him for bullying the smaller chicks! He mostly leaves the D'uccles and cochins alone, but he bullies the silkies and sometimes the Japanese terribly! This isn't just minor pecking-order pushiness- I've seen him full on holding a chick down and head pecking- hard. Has anyone else run into issues like this? Did the bully calm down after a while or...? Could use some advice. Edited because of my obsession with fixing typos.
