hey everyone! We asded 8 pullets from TSC to our existing 3 hens. They new girls are almost 18 weeks and only one of the Lavender Orpingtons is somewhat aggressive towards me. She always rushes towards me when I come in the pen or yard and pecks at me a lot. Today I was petting a black australorp and she she bit my hand and left a mark. I have never had a chicken like that in our flocks and don’t want her to do it to my children. Any suggestions? Or is this normal or something they will grow out of?
