I have one hen that bites me sometimes on the foot. I usually pick her up and give her attention. If I put her down too soon, she'll bite again. I am wondering if she is doing this for attention or if it is a dominance thing. I don't believe she is at the top of the pecking order--maybe 2nd in line. When I pick her up we are face to face and she could peck me then but she doesn't. She has pecked my hand and the top of my head the other day when I leaned into the coop. One other thing is that I may be giving treats too closely in time and so she associates treats with pecking. I am not consistent in the treats and in fact as I think about it, will stop. I find the chickens have about a 60 second memory span. They rush out as soon as I arrive home but by the time I bring out the treats they have forgotten and left!!!! Silly birds.
