According to http://www.nutrenaworld.com/knowledge-center/poultry/how-much-does-a-chicken-eat/index.jsp Laying bird needs 1.5lbs of feed per bird per week. However, I went through 100 lbs in 5 weeks. I have 8 chickens. So it's 2.5lbs per chicken per week. Do they really need only 1.5lbs per chicken per week? The cost for 100lbs feed is $36 so it's about $7.20 per week. This means I spend $28.80 per month. Yikes. If I follow that link, it would be $17.28 per month which is much less expensive. Thoughts? Thanks. Notes: MY 8 chickens are 7 months old. I buy feed from closest ranch: http://www.ranchfeedandpet.com/ I tried fermented feed for a few weeks but it got too nasty. It was fine for first few weeks then last few days before I dumped the whole thing the top layer was all white. I can't stand the smell.
