My chicks are almost 3 weeks and I'm wanting to make both a hanging waterer and feeder and I'm wondering what is the most practical size to get considering I'll have only 3 hens, and I think will want to hang both inside their future coop. Would a hanging 1 gallon waterer be adequate? 3 gallons seems like overkill! How about for a feeder? Any suggestions would be very appreciated!! Thank you! I can easily see how to make a feeder that could hang (a coffee can on a wider round dish, with a few holes to let the food into the dish, and two holes through the pan and coffee can to string up the feeder. But how can I make a hanging waterer? Maybe I just have to live without being able to hang it?
