My 3 EE pullets are around 6 months old, about 6 weeks ago I noticed they were eating every feather they could find, not pecking each other though, but if it was a loose feather it was eaten. I immediately put them on grower since they had been eating layer and scraps for 2 weeks. Feather eating diminished but did not totally disappear . They have been on the grower for 6 weeks now and they are back at eating any loose feather they can get to as fast as they can get it. They also don't appear to be getting larger, almost stuck between banty and LF sizes. I'm using the Purina grower as it's the only kind I can get out here. They don't like it that much either. I do supplement with meat leftovers and trimmings on occasion. Not free ranging, in a run 8'x5'. We have had fecals run and no worms. What have I missed? What can I change? Changing the food is going to be a problem though, every place within 60 miles sells Purina.
