I have 6 goats-2 mommas and 4, 9 month old babies. I let them out to roam on 4 acres around my house at 8 in the am. I feed them at 8am and clean out their goat house. In the evening, around 6pm I feed them and then about dark I bring them back into a large pen with a goat house 18X12 feet and I lock the gate. Problem is lately, they don't want to go back into their pen/ goat house? I did see a few mice, but nothing else. The goat house is air conditioned and there is heat for the winter. I dont have either on right now except a fan cause it is around 58 at night here. Could they be scared of the mice? Anyone else have this issue. Maybe they just like hanging under my large porch which is where they spend most of their time. I am just concerned that there is something I am missing.
