I have 25 hens and 2 roosters. They have a large coop, their run is a electronic fence of about 1.25 acres. They share this with 2 goats. We are thinking of adding 1-2 guinea pigs. My question is: can i put them together in the same fenced in area? This fence is 5 strings 3 - 4 inches apart starting at 3 inches above the ground. We also plan on adding 5 ducks this month too. I can extend the fence another acre too if you advise me too. Thanks so much for your input!
