The feed I buy for my ducks increased by $5 in the past year and the bags went from 50 lbs to 40. My birds usually through 80lbs of feed in 2.5 weeks. I'm spending so much on feed, that I've been giving them wild bird seed(which is $10/20lbs) and grass clippings(free) as snacks during the day. It cuts down on how much feed they eat. Next year they are going to get an entire garden dedicated to their diet. I got the seeds this year, but didn't start them early enough.
