I like this idea a lot. I have several remote locations and I could leave a sealed drum out there at each and have my hubby fill them. It would get the feed out and get the heavy lifting off me! It would be an initial investment, but there is a place down the road that sells the plastic ones that are second hand for a reasonable price.
We have tons of hawks here. We are right on the river so this is a Mecca for wild life. This I think is a spring birth that has occurred over where they never knew about the feed before. Suddenly, they are coming from far and wide!
