I got my Rhode Island Red with three other pullets to add to my small flock. They were 4 months and are now five months. Two of the pullets are Rhode Island Reds, and one is sweet and gentle, but when I get near the other one, she attempts to peck me. What can I do other that just holding her and all of that? All 4 of the new girls are skittish and flighty, but I mostly raise my hens from chicks and don't have experience with rude ones. I'll take all of the advice I can get. Thanks!
