I’m new to the chicken world and wondering if anyone can give me insight on what may be wrong. She’s 3 months old and has a coop but free ranges during the day. There is an old dog house under the porch or the house with old cedar bedding in it and they like to get in it so I’m wondering if this could be linked to her illness. She sounds raspy when she makes noise and she’s coughing or sneezing I can’t tell which. The main concern is the open mouth breathing. Can anyone give me an insight?
