i have 2 silkies that are about 13 weeks or so. they seem to have trouble seeing enough to maneuver the ramp in and out of their coop. so i had read somewhere on here that someone had trimmed the fluffy feathers around their eye and that it helped but i'm not sure how far to trim the feathers? do i trim all the feathers on the side or just the few right around their eyes? any help would be great thanks.
