ok...i'm pretty emotional right now...here's the days events. I have 3 Red Star pullets (approx 24 weeks old) and have been enjoying fresh eggs for a few weeks. I noticed just yesterday that my favorite chicken, Garnet has been getting picked on my the other two. So much so, she has been hiding in the coop and seems afraid to come down into the run. Mostly, my one chicken, Topaz picks on her, but then the other one, Ruby, joins in. Garnet seems frantic to get out of the run. I'm not sure if this is just typical pecking order antics or something more....any insights? Now for the horrible part. I came over to the coop and opened the door to give the chickens some treats this morning and Garnet came out of the coop and joined the girls in eating up the corn. As soon as they were done, the two girls attacked her and Garnet ran right past me out of the run into the yard. Unfortunetly, my hound dog was out and immediately attacked her. I was horrified! We ended up getting her away from the dog and checked her over. She was not bleeding or had any puncture wounds on her but lost a ton of feathers. I am unsure if she has anything broken. I cradled her for about a half our and she was very subdued. She has always been my friendliest chicken and likes to sit with me and let me pet her when i'm out letting them roam around. I put her in one of our dog crates with some hay, food and water next to the orginal coop but am afraid to put her back in the regular coop since i am unsure if she is injured and the girls would pick on her more. My plan is to monitor her this way for the next few days to see if she recovers. Any thoughts on my ways to proceed? IThis is my first time owning chickens, so i am quite the novice. Any advice would be helpful.
