Someone forgot to tell my RIR pullet this. I normally hand feed my 3 chicks some treats a few times a day. They are 10 weeks old. My 2 BOs are good girls and politely peck the treats from my hand. My RIR will peck really hard and then bit my palm or my fingers. I started out giving her a little poke with my hand each time she did this. Now she looks for this coming and peck, bite, jump back. So I started making a verbal correction but this scares all the birds. So now if she bites me I just move my hand away from her and not let her eat from my hand anymore. She doesn't like this and tries to get to my hand and pushes the other birds away. And it doesn't seem to be working. I got so mad at her this morning I stalked her into a corner. Of course I effectively freaked out the other girls because they always stick together. Any suggestions? Just continue to not hand feed her when she shows aggression? Thanks.
