The lady who originally rescued my hens from a city park and nursed the one with a dog bite back to health had them very tame because she treated them all the time. I don't do that because they are free range and I don't particularly want them pestering me all the time anyway. I use an automatic feeder too so they really don't need me however I noticed something interesting today. The feeder has been empty since yesterday afternoon so this morning when I went out to do the chores all three barred rock hens came running to me I thought that was pretty cool and threw out some scratch for their effort.
