We have had a bad week for our chickens. I had 2 hens just start of laying. A EE and RIR. Last week a raccoon raided the coop when when we did not get home before dark to shut them up. The coon killed my RIR leaving the EE as the only chicken. Worried that my EE would be lonely we went down the street and picked up another chicken. This was on Saterday. This chicken was a little smaller. We showed the new bird to the EE and she pecked her back a few times but besides that it was the only interaction. We kept the new bird separate. After having the new bird 8 hours I noticed she had one watery eye.. then began to notice she was very rattley when she breathed and breath with her mouth open...there was clear nasal discharge. I became increasing worried that we had gotten a sick bird and took her back to the farm I got her on Monday morning. (So I had this new bird Saturday morning to Monday Morning) I disinfected the coop with spray that says it kills flu, bacteria and fungus. I even sprayed some of the grass in the area the new bird had been hanging out... . and changed all the bedding. I gave our EE some electro light water Last night was the first night she spent in the coop since the raccoon attack (we been letting her sleep in a dog crate in the house and the other bird was sleeping outside in the coop) . She was reluctant to go in. This morning I find her sleeping by the door of the house with her head tucked. If i listen closely I hear a soft 'growling sound' almost like she is snoring. She has coughed two times... once while drinking water and another when she was sleeping and woke up. Her eyes are bright and not watery and no snot. But I am soooooooooooo worried she caught some sickness from this sick chicken even though they where not interacting together. Is there anything I can do or give her to ward off an Respiratory infection before it starts??? I have also not gotten any eggs from the EE since the raccoon.. unless she is laying them somewhere other than the coop. I really want to bring in another bird companion for her too..
