My father-in-laws border collie knows a few commands like beg and bark but she wasn't trained to heard. She does run up to the cows and bite their ankles, if someone goes and starts up a car during the winter she will run over to the camel pin and bite the camel out. Our first chicks we hand enclosed in a pin outside and she wouldn't get away from it. She LOVES to go get cows in and wouldn't even leave for that. We'd try to get her away from it but it wouldn't work. Finally they got big enough we moved them into a large open pin and would only let her come in around them with us. We wanted her to get use to them but not attack. We told her no and distracted her when she seemed to interested. Well finally a few weeks later my father-in-law checked on the birds and went to the barn. I went out to check them only an hour later. I got in the pin and there she was with something in her mouth. I yelled a few times not realizing what it was till she finally let go and the poor roo ran off. I yelled at her to get out and she had found a spot under the fence. I got my FIL and we went and checked for the chickens. All our ducks/geese were fine. We found about 5 out of 20 that wasn't touched. Then we started finding the others everywhere. There were even some on the outside of the fence in different spots. One side of the fence is 4' tall and the other sides are 8' tall. She killed 6 that we found (one died after finding from a serve neck wound) and we never found one. She did all of that only in an hour. My FIL, my husband, and me all yelled at her and gave her a spank (she's probably 5 yrs. old). Since she is a very skiddish acting dog we only had one other time that we know of that she almost got a hold of a month old chick that got through some wire but I seen her and yelled before she did anything. So be very careful with dogs around chickens. Since it is a puppy you have better luck at training it to not attack.
