My 6 chickens have been moved to the coop and I need to catch then to move to pen in yard so they can forage but when I have had to catch them to check for mites or other they have become so frightened of me they will not come to me any more. not even with scratch in my hand. I can't get them at nite because they need to be in yard only during the day. any suggestions? It has been over 2 weeks and they have't warmed up to me yet.
