I've been wanting to make suet for years!
It took a full day to render the suet (I neglected to chop the fat into smaller chunks), so it was nearly bedtime before the kids had a chance to stir in the seed, nuts, and dried fruit. They cut and inserted twine, and delivered filled muffin tins to the garage to freeze overnight.
Our Christmas tree was repurposed and moved near the bird feeders, suet ornaments were hung. We waited and watched for the birds to flock to our tree and devour their special treats.
Instead, we watched with both horror and amusement as the squirrels greedily ran off with them.
