Please shed some light. One guinea was found near death and frozen on 1-7-2015 late evening. I brought her in and put her under low heating pad with sheets and tee-shirts. In the morning I checked on her and she was alive. I gave her small amount of water and she drank it. Then I tried ground corn and meal worms, she ate that too! I have placed her in a small unused bathroom with old rugs, food and water. I check on her often. She is walking around gingerly and has eliminated as normal. How long should I wait before putting her back outside. They(other Guineas and Chickens) have a coop that is opened daily as the like to exit even if not very far. I live in northern west Michigan and it's been cold this week. Please advise as I don't want ot keep her in too long and then create another problem. Thanks bird people!!!
