I purchased 10 fryers. They are approx. 4 weeks old tomorrow. This isn't our first time raising fryers. They are kept on pine shavings. The shavings are replaced every other day. I believe in keeping things I'm going to eat...clean. They are in a heated enclosure. Because of the shavings, we have always made sure to watch for any birds that have plugged rear ends...so that hasn't been a problem. They are fed meat bird food and fresh water free choice. Occassionally they are given fresh produce, usually lettuce. Everyone has been doing well and thriving until yesterday. I noticed one of the birds not interested in eating and it appears slightly smaller in weight then the rest. When I replaced the water this evening it did take a quick drink, but after I brought it to the waterer. It spends a lot of time standing with eyes closed which for people that have these birds, standing other than to eat/drink is unusual. It isn't at all interested in food. I'm not positive if there is any discharge from the nasal area. Within minutes of drinking water it shook it's head a few times and I did see moisture. This could have been from the drink as I don't see discharge otherwise. It can walk with no problem. I just don't see any signs of actual disease or injury. I have separated this bird from the rest in a small enclosure with food, water and heat. Although these are meat birds, I care for the birds we eat just as well as the layers so I'd like to find something to make this guy feel better. Obviously the feed store is closed until the am so I'm seeking advice from others in the mean time. Thanks in advance for any help.
