My husband just installed two PVC Pipe feeders for the hens. They have saved so much space in the coop not having the large metal feeding taking up so ground surface area. The only problem is that the hens are throwing all the food onto the floor. We didn't have this problem with the metal feeder. Did anyone else have this issue? Any suggestions on how to fix it? We installed one with our silkies as well and they seem to be eating it out of the feeder and not throwing it on the ground, it's just the big girls!
