I had a flock of 7 guinea fowl a few years ago.. living free range in my mango orchard. I had them for about 2 years, raised them form keets. Sadly I lost most of them in a few nights to feral dogs. And I had to re home the rest as I was unable to stop the dogs getting in. Now I have the land all fenced and walled in.. and its safe now from dog attacks. I was looking for some young birds for many months. Finally a pet shop got 4 keets for me. Yesterday I got them home.. I was very excited. However, I noticed that they are coughing a lot. They are not sneezing, and don't have any bubbles or mucus in their eyes or nostrils. Poops all normal and eating and drinking normally. Any idea what could be wrong? I got them in a small pen away from my chickens... with water with added vitamins, and am feeding high protein chick food, mealworms, and hard boiled eggs.... some grain as a treat. They are very different to my other keets I had before... they are very scared of me and wild acting.. jumping about and won't come near me even with the insect treats.. and its when they get scared and start running about they start the coughing. I have seen no open beak breathing, or gasping. Just the coughing sounds, which sound a bit like they have mucus in their lungs. Thanks for any advise... I am very worried about them.
