I'm currently in the process of raising 12 chicks. I have a 4x10 tractor setup, which I've already been warned about raising in that size tractor, however, I have a fenced in yard...about 1/4 of an acre. I'm new to this and was curious if I'll be able to partially free range my chickens in the yard with a chain link fence that is 4 feet tall. The last thing I want is to be chasing chickens through my neighbors yard. There's no predators such as dogs in my yard that pose any threat...just wondering about that fence height if it will be tall enough.
