I am looking for a possible new way of feeding my small flock. I have four birds at the moment. We have been using one of those quart(?) size plastic bottles with the screw on bottom, gravity feeder that we got for them as chicks. This lasts about two days, they forage in our backyard at will. But it gets tipped over and when we leave for the weekend we know they run out before we get home. Been thinking about one of the hanging feeders. Seems quite large, though obviously I don't have to fill it. But we are fighting to keep rats away. We kill a few and they are gone for awhile and new ones move back in. It happens every year since we bought our house and this is our first year even having birds. Kind of frustrating. Anyways we have been covering the feeder at night with a big plastic flower pot and putting a rock on top. Except for the one time some hay got stuck under the pot and I found a baby rat under it it has worked well. Though not sure what the rats are eating.... wondering if there is a height that would keep the rats out of the hanging feeder, or will they be eating out of it too? The hanging feeder would be hanging from a rod bolted into a tree that is the center of the tarped pen. The tree is really slick barked, I can't imagine they could climb it. But I don't' know how they get into barn rafters? Any comments from your experiences would be appreciated!
