Sorry if this is a sensitive topic, but does anyone have a good home option for a kill cone? I am going to euthanize the banty tomorrow, but I don't have one here. It doesn't look like they sell them at tractor supply, unless they go by a different name.
For a quick cone that won't be needed for numerous birds I would use a bleach jug or any plastic jug of similar shape. Cut out bottom, cut neck of bottle just below cap threads or possibly a bit further down if needed and turn it upside down and run a screw through it into a tree.
You could also use a pillowcase if you have one you can throw away. Cut a hole in the corner and use a big zip tie to attach it to a screw you bury halfway in tree trunk. (Use a second zip tie to gather all the extra material into a bunch so the bird is held snugly)
