My pullets are about 9 weeks old. I've had them since they were chicks, but they did not like being held unless they decided to roost on me on their terms. Now 2 out of the 5 peck/bite by finger/hand as I'm reaching for them. I understand that this could be threatening to them, but I want hens that I can handle! Will they stop with time and more handling? I've found with the ones that struggle, that if I hold them (feet still on the ground) until they stop and relax, they don't panic as much the next time. Is this right?
