We have 3 hens. One has recently hatched 6 little chicks. She and the chicks are separated from the others at the end of our run. Recently (it started when the broody was still sitting on her eggs) the other 2 hens have started charging us and pecking at any exposed skin. They are sneaky too. They wait until our backs are turned. Could this be a reaction to the other chicken being separated? Can chickens be jealous? I know they are extremely curious now that the chicks have hatched. They are over at the divider fence often calling loudly. Is there anything we can do to stop their aggressive behavior? One pecked my 5 year old on the leg today and drew blood and left a bruise.
