This is our first year with chickens and our dog, a boxer has only been introduced through the fence to the chickens. Today I am walking him near our coop and he runs around the back. I followed him only to find him pouncing on my favorite chicken, Ms. Hook a Bantam Polish. She is the sweetest thing with a beautiful crest that I trim so she can actually see. She is meek and mild sticks close to the coop and nest boxes and loves to be held. She also tends to get stepped on because her limited sight. Somehow on a very cold windy day with no other birds out in the yard, she came out and managed to find a gap where the fencing had come away from the side of the coop and escaped. I pulled Leo off her but he managed to pounce at her two more times before I got him fully under control. In tears I took him to the house and went back to find Ms. Hook. I took her in and looked her over, No blood, no visible injuries just a few loose feathers. I put her in the basement in a dog kennel for the afternoon for observation. As of this evening she is back in the coop and appears to be normal. I am so thankful!! I wish Leo would get along with the birds but at this point have little hope for that.
