Hi, I purchased some chics from a local feed store. I was told that they are about 4 weeks old. They were already being kept outside and it gets fairly cold here in West Texas. I have noticed that they are sneezing and seem to have a gurgling sound when they breath. I was thinking they may have a cold. I am newish to having chickens so, don't think I am crazy. If you have any help, let me know. I have added pics of the babies.
