I was giving my EE some herbs and then started petting her and giving her some love and my EE/silkie was looking at her mad like and walked over to her while I was petting her like she wanted to peck her. When I let the EE go, my EE/silkie grabbed the back of her neck and jumped on her and literally attacked the poor EE. I got her off and my rooster gave her a quick peck to set her in her place. My EE jumped up to the perch, clearly freaked out from what just happened. They normally get along just fine and got along after this. So my question is, can chickens get jealous over attention?
