My two turkeys (female) have been fighting, on and off, sometimes even drawing blood. The brown turkey (sitting in the chair) seems to be the aggressor. They get to free range all day and they have a 4 x 8 ft pen to sleep in at night. The fighting occurs during the day, when they’re running around. Any ideas why they are fighting and what I can do to prevent it? Is it just a pecking order thing? Thank you !
