About 3 weeks ago one of our three chickens got attacked and didn't make it. Ever since I have left the other two in the coop so that whatever got it didn't come back for more.. I just let them out for the first time since then yesterday. I have raised them since babies, I would say their close to about a year old now and all have always been very nice. Blondie has always been a sweetheart to me and everyone else around, and Penelope has always kind of had an attitude nothing seriously but when your walking away she tends to run up on you and peck the back of your leg but she would stop when told to.. The first thing that blondie did when she walked out of the coop was peck at my leg, she has never done that before. It wasn't just a usually peck because when she went to do it obviously I wasn't used to her doing that so I tried to shoo her off with my leg and she held on and puffed up like she was actually mad. Now anytime she sees me walk outside she runs up and starts trying to peck at me. Not such a big deal until she just did it 10 min ago and kept trying to come at me. Even tried to turn around to put her claws to me. I don't know what the problem is?! Will she always be like this or is she just mad or something?! What can I d to show her I'm in charge and not to "bite the hand that feeds you"
