I am acquiring a new hen today. She is the only hen of her old flock that survived a dog attack, so we've agreed to adopt her. We currently have 6 happy, healthy hens that are approximately 8 months old. I plan on introducing her slowly. We have a section of the run fenced off for her to have her own space, but be next to the other chickens. We are in the beginning of a real cold snap, highs in the single digits and lows below zero with some wind. I plan on keeping a crate or box covered with a blanket and filled with straw in her small run during the day. I will check on her to make sure she has access to fresh water. At night we plan on keeping her in the garage with a heat lamp if necessary. Apparently new chicken is recovering from a puncture wound. The wound is healing, not weeping or open any longer, but she has liquid stools. I’m told she is eating and drinking normally and has even laid an egg or two since the attack. My concerns are about keeping her warm enough since she’s been housed indoors for the last week or so since the attack. I’m also concerned about her health and introducing her to my flock. I plan on keeping her quarantined, but am not sure how long is necessary. Any thoughts or ideas from more seasoned chicken keepers?
