I think one of my girls is sick and I don't know what to do. She was fine this morning and I came home on lunch and she's all by herself in a corner. Her color seems off, wheezing while she breaths and she won't let me put her down now that I've picked her up ( she NEVER let's me hold her) I don't know what to do!
If you've put her back in the coop, go back out there 'n get her. You should make sure she's warm, and isolated from contact w/ others. Most probably, others will show similar symptoms. If so? Isolate them as well.
Give all of your birds an astringent solution of Apple Cider Vinegar at the rate of four teaspoons to the gallon (but not in galvanized containers), as this will help them more easily expel mucus, and remove the coatings w/in the mouth, throat and intestines, improving uptake of nutrients/vitamins, which will also serve to boost their immune systems.
This could also be the result of internal parasites, for which you could worm her (and the rest) w/ fenbendazole at the rate of 20 mg/kg for three consecutive days. This is an extremely effective anthelmintic against all internal parasites except tapeworms at this dosage, and it's been proven safe to levels 50 times higher ...
Keep a close eye, from a distance, on the rest of your flock, and be sure 'n update this thread w/ any other symptoms you may discover.
