Bear with me ... as my story is sort of lengthy...but at this point I am so worried and not sure where to turn. I had a flock of two chickens...they were best friends and did everythign together. ONe of my chickens had a blowout that she did not recover from causing us to put her down. Leaving us with one lonely chicken. Because winter is fast approaching (would you believe it is snowing today in CT!) I decided the best thing would be to get my chicken a friend. I got her a nice fuzzy chicken and after a week they were getting along great....walking the yard together. Although I have to admit this new chicken spent more time then usual in the coop and i often had to lock her out of the coop to get her use to life in the yard. She seemed to get my chicken in this habit as well. I would push them out of the coop in the morning, lock them out, and send them into the yard and they would be fine...coming to roost in the evening. Well one day my dogs ... that have never so much as ruffled a feather on my other two chickens killed my new chicken. I believe it traumatized my little girl and now she is sad and scared. She is spending most of her time in her coop. But i am not sure this is a lingering result of her learned habit from her time with the other chicken... or if it is due to the weather changes. It got really cold really fast here, barely breaking 40's somedays (30's over night) ... and as I said it is SNOWING today. Full out snowing...even gathering on the ground! Its miserable and wet. Today I go out to check on her and there are feathers EVERYWHERE. And honestly the season is right for moulting but I am really worried it could be something more. Does anyone have any opinions????
