My hen Rosie is gapeing and wheezing very loudly and has been for about five hours. I just got home from visiting family, left yesterday morning and got back noon today. When i got home i noticed my chickens had run out of food, i thought i had given them enough for the day but i was wrong. I gave them food and all were eating fine. When she started eating Rosie was fine, but around halfway she started wheezing in between pecks until i moved her away from the food. I fed her until she was full by hand, i didn't let her rush so she wouldn't aggravate whatever was wrong anymore. Rosie has always had issues with her breathing but she's been fine since i put her on antibiotics around two months ago. I let her be for a while thinking that maybe she would fix herself but she's still wheezing. I gave her some organic cough syrup to hopefully soothe her which worked as a temporary fix before, (basically just honey and eccenatia) and one mil Tylan50 and set her on the roost where she still is now. I am very worried now, i don't know if there's anything more i can do for her. I wanted to separate her from the others but she gets what I'll describe as separation anxiety whenever i try, and i feel like it would be better to keep her stress down. Rosie has had problems since i got her, first it was bumblefoot and then her respiratory infection. After her first round of antibiotics she laid her first egg with me, her breathing improved and i haven't had any issues until now. i thought she was just inhaling her food, and planned to start fermenting the chicken feed this summer when i have more time. I'm going to start fermenting tomorrow, and work it in as a treat to start so it doesn't stress Rosie just switching to another feed. I don't know what else i can do. Please help, thanks in advance. Rosie is an amerucana hen, just under two years old. A little on the small side I'd guess four to six pounds (my other hens are all around eight). I have a flock of four hens and one rooster, i have more hens planned in June to balance my rooster. Advice is appreciated, thanks in advance. The picture of her is from before she got sick, i don't have any pictures of her from today and she's in the roost now.
