Are Cochins known to be particularly poor fliers? Our Cochin pullet (15 weeks) can't seem to get off the ground more than her tiptoes. She can't get on the roost with our SLW and BO who are her same age. Is it just her body type and feathers or is mine just a prima donna? It's pitiful to see her looking up at her sisters, wanting to be there, too, but not being able to get to the roost.
