Does anyone have an opinion on staggered roost bars having an effect on pecking order problems at evening roosting time? My roost bars are spaced 18" apart, same height, side by side. At bedtime there are frequent squables/pecking order issues. With my bar arrangement, the birds have easy access to each other and dominent birds pick on less dominent birds. Would it be better to place one bar a foot higher so the dominent birds can go high and make it harder to reach less dominent birds on the lower roost bar?
