So we have 25 Buff Orpingtons in our brooder at the moment... They are about three weeks old. We play with them a bit (though they are definitely frightened of us!), feed them and give them water. Is there anything else we should be doing? Inspecting them for health issues? How do we get them used to being handled? We have put them outside in a small sheltered pen for a few hours a couple of times and they were very happy. Thanks!
