I finally broke down and bought the big enormous bags of bird seed. After this morning, I didn't have any choice. There's just too many birds, now – all of the babies from the ducks/pigeons have grown up, and now they are EATING MACHINES.
Last week I spent $25 on 30 pounds of various seeds (which I blend together for my own special mix)(stop laughing). The food was gone by last night. Today I spent $30 on 75 pounds of food (40-lb of wild bird seed, 20-lb of cracked corn, 15-lb of songbird mix). This batch should last until mid-July. If that holds true I will have cut my costs to feed these freaks by 40%.
After PetsMart I went to Wal-Mart and bought a 19-gallon washtub thing in which to put the seed. Then I painstakingly mixed the three bags, using a wooden dowel as a stirrer and my beloved Looney Toons mug to portion out the seeds to get just the right blend (three cups wild/two cups corn/one cup songbird - STIR!). I'm storing it in my utility closet:
For perspective reference, the litter box beside the bird seed container is one of those GIGANTIC models. I'd say the bird seed tub is about up to my knee.
