I have lots of thoughts on livestock intelligence. I had one cow who was plenty smart. Sheep are smart for being sheep. One sheep leads them all and that can be over a cliff. I think I have told my chicken story before. They can't see in the dark so all go to roost before then. I don't have electricity in my barn so I went to lock up late and one chicken was still 'up'. She followed me all over, clucking and cackling like she was reading a phone book. She never shut up. I finally leaned down and scolded her, What Do You WANT?! She stopped, looked me in the eye, turned and ran down the stall fronts. Ran back to me, Ran down the stall fronts, Ran back to me... I followed her around the corner. A horse had kicked the mounting block away from the wall. This chicken had come from an Amish place so her wings were clipped and she could not fly to get up on a stall wall to roost with the rest of the girls. So, I had put a mounting block up against the wall so she could jump up to a cross beam to get as high as she was comfortable. Lassie could not have communicated better to get someone out of the well. I don't care for goats. But I really like my chickies.
