Hello, Newbie here; We are excited to be getting our first three hens (for egg production) and a hand built coop next week and have been rigoriously researching feeders and waterers. I've found two main material feeders and waterers on the market, galvanized metal and plastic. Does any one have any preferences that they can share? The "make your own bucket feeder" posted on another thread looks pretty amazing and inexpensive which is attractive but I was wondering if anyone had any feedback on the metal ones as well. Cleanliness? Bacteria growth? Etc. We live inland in Southern California and we have very hot, dry summers, my only concern with the metal is that the surface might be a little hot for the birds come August or September. Obviously shade would keep the feeder cooler, which we plan on but still when the temp hits 110-115 I want to be sure my birds can still eat and drink. I would appriciate any comments or suggestions. Thanks!
