Chickens are pigs, but that's a bit extreme.We adopted our 6 chicks from TSC. When we were looking at what type of feed to purchase there was a 35# bag and a 40# bag. I was looking at the ingredients and comparing. I asked the worker how long she thought the 40# bag would last for 6 chicks, she told me, "About 2 weeks." I thought I heard her wrong or she misspoke so I asked again, "About 2 weeks." EAT UP CHICKS!!! LOL
