Pour packets of gelatin into water; let sit for 1-2 minutes.
Transfer gelatin water to a saucepan; bring to a boil and stir until gelatin has completely dissolved.
Remove from heat and let the gelatin cool/set for 5 minutes.
Stir in the birdseed.
Line sheet pans with parchment paper; place the cookie cutters on the parchment lined pans.
Using a spoon, scoop the birdseed into the cookie cutters; press down on the cutters with another piece of parchment paper to compress the birdseed.
Using a straw, press down and twist back and forth at the top of each birdseed filled cookie cutter; this will create a hole for the hemp/twine.
Place the sheet pans in the freezer for 20 minutes to allow the bird feeders to set.
Take the sheet pans out of the freezer and allow the birds feeders to sit at room temperature for 10 minutes.
Delicately, push the bird feeders out of the cookie cutters with your thumbs.
Thread a piece of hemp/twine through each hole and tie to create a loop for hanging.
Scare the birds!
