I am getting some chicks in a few weeks and am trying to lay in supplies now. Do I REALLY need a chick waterer or can I use a regular waterer? If I need something smaller can I not use a weighted low plastic dish? I will only have 6 maybe 7 chicks after I give away the other 20 the next day..... Also, when can they figure out a hanging waterer? I want to hang everything to keep it up off the floor of their coop..... Thanks!
