Pelletory . . . .was wondering if you knew the answer to this question re nyjer feeders.

Just bought a brand new nyjer feeder (c. one a month ago), and not one finch/bird has visited this feeder. I have other feeders in my back yard, which attract lots of birds including finches. I was wondering if you knew (or anyone else :o), if the size of the holes (they seem to be slits) are too small, and if the steel perches would stick to the birds' feet in freezing temps. Could these be deterrents. I thought maybe I could widen the holes a bit--it appears to be an acrylic cylinder. Thanks, Snug
