This evening when I went to shut up the coop I heard what originally sounded like snoring. I traced it to a mixed breed banty hen that is about a year old. I have brought her in the house. She is wheezing, head up a bit and beak open. Since she has been in the house she has begun to sneeze. Rather large sneezes and loud. No mucous in her nostrils or mouth as of yet. The wheezing isn't constant. and the sneezing began after I started massaging her crop and neck. There is basically nothing in her crop. I was able to get her to eat some cottage cheese and she was hungry but didn't eat a whole lot. Will start antibiotics in the water in the morning along with vitamins. I am assuming that this is a cold..... BUT I did spray some eco-friendly bug kill in the cracks in the coop several hours earlier. She was not in the coop at the time. There is also a light sprinkling of DE on the floor the grass is a few weeks old (we don't use chemicals on the grass) And we have not had rain in over a week the temperatures are in the 80's with a breeze. They all free range. Any ideas as to what I am dealing with? And any other ideas as to what else I should do to keep the rest healthy? I'll make her eggs and/or oatmeal in the morning.
