I have two frizzle Cochins that about 10 or 11 weeks old. I had them in them in a separate cage for about a week. I take them in at night since I can’t integrate them yet and I’m afraid it’s too cold at night for them (getting down to 40/45). I let them in with the my three 9 mo old girls today (Cochin, Rhode Island Red, and silver laced Wyandotte). The immediately went after the poor baby. The larger one was pecked to the point of bleeding by my red. I separated them again. I knew they would peck to establish the order but is it normal to have them draw blood? Also would they be okay being out at night? I just feel like they aren’t very feathered.
