We have 20, 8 week old chicks and they went through 50lbs of feed in 2 weeks. We have a homemade feeder with a 3" deep pan around it and their floor is sand, so I don't think waste is an issue. It was my understanding that they would do 50 pounds in a month. We buy organic feed from our coop, so this is really expensive. We're fixin to cull 5 that we got for meat birds, so that ought to help. Oh, and, they are in a run all day eating whatever comes their way. Do they really *need* that much food or will they just eat it because it's there?
