I just got 3 8 week old chickens, and I am going to get 5 more tomorrow. I have been throwing feed on an old barrel top, is there something wrong with that, and do i need a feeder? and with my 8 chickens, would a 1 gallon waterer be good for the chickens? I am outside feeding and watering them every day, and I want to make sure I am doing this correctly. Thanks for any advice.
