Hi, our 10 week old Barred Rock pullet is not acting like herself. She usually comes right to me and lets me hold her, and she usually bosses around the other pullets, but she hasn't been doing that today. We found out that she has an impacted crop. She is asleep with the other chickens in the coop right now, but tomorrow at the crack of dawn we are going to put some grit in there coop to help her digest. Is there anything I need to know?!!?! We are new to chicken keeping.
