Hi there! I am new to all of this. My husband just built an amazing coop and we are looking into watering and feeding systems. I like the cup waterer system like this http://beaktime.com/water.php but it seems like it would be cheaper to make if I can find where we can by the cups. Anyone know of a place to buy these online? Really, that's all it is, right? Along with the pipe and bucket... Just a little back info, we are getting 8 silkie chicks in a few weeks, so we have some time since they will be in the brooding box for 5 weeks or so... Any info you may have would be greatly appreciated! Thanks!
