Please choose the correct ending to complete the given sentence: Pets and Animals: [header] How to make a bird feeder [title] Poke a hole in the bottom of a yogurt pot and pull a string through it. [step] This string should be long enough to dangle the feeder from whatever position you intend. Tie a knot in the string on the inside of the yogurt pot, such that the end of the string cannot then be pulled out.

Ending1: [title] Add a tarp-covered bird feeder liner, not the plastic ones that you'll be using for the chicken feeders. [step] This will be used when the birds are used to hopping and running about. Ending2: [substeps] Use a drill bit to drill holes through the bottom of the yogurt pot. Alternately, use a small needle or a hole-puncher to puncture the bottom of the yogurt pot. Ending3: [title] Melt the lard in a pan over low heat. [step] Remove it from the heat once melted and stir in breadcrumbs and birdseed. Ending4: [substeps] You may want to attach a couple of chicken boards to the bottom of the pot. Make sure that the wooden board has no holes to push in; you don't want to puncture holes.
