I have 10 4 month old hens and a rooster. I also have an additional 5 hens that are about a month old. The first batch I didn't handle them much and they run in terror when I come near them. So on this new batch I thought I would handle them on a daily basis to help them get used to me. That's not working either and I have stopped due to possibly stressing them out. I read on and on about how people's hens are so loving and follow them around and jump on them etc. Are my hens still to young? What's the deal? Thank you.
