Sudden sick chicken

These symptoms are often associated with so many diseases accurate diagnosis can be difficult. I feel it is safe to say most of us have lost birds with these symptoms without ever truly know what was the cause. I personally would never let a sick bird stay in the coop; both for the safety of the flock, and the safety of the ill bird. Chickens will kill birds that aren't acting right, its in their nature to help keep disease from spreading.

Im going to give you a list of potential causes of your birds ailment based on my experiences with these symptoms

First, I check their crops. Its located at the base of their neck. If it is swollen up, (about the size of a softball) and hard, impacted crop may be the problem. This happens when the passages from the crop into their gizzards gets blocked up by an obstruction of some sort. It can be fixed, however the procedure isnt pretty... If the crop is limp, or you cant seem to locate it at all, this means she isnt eating at all and your issue can probably be found elsewhere.

Second, check the vent. It should be clean and dry. Maybe she is eggbound? Usually an egg bound hen will stand in an upright position as if attempting to lay her egg. Also, curable with a little effort. Another issue common egg laying issue is internal laying. It's pretty easy to spot in the advanced stages. Her vent will be extremely swollen and the skin around the area will have a yellowish hue. Its not treatable without an exspensive surgery. While examining the vent, look for parasites. If she has a heavy parasite load this may be causing her to be lethargic.

If neither of these turn up concerns, your left with potentially a much more complex internal problem, or disease. I would try her on Duramycin if all else failed, its a broad spectrum antibiotic which has helped me in many situations similar to your own. If its going to work she should respond relatively quickly to the antibiotic. Sadly, often times hens come down with cancer, its a common issue, especially ovarian cancers. This is always something to keep in mind.

Best of luck, hope this helps in some way! Keep me posted, if you can pinpoint her problem I may be able to help in giving you more advance directions in treatment!

 

If you could get a stool sample checked for worms, coccidia, and bacteria, today, it might save some guess work. Coccidiosis causes diarrhea, lethargy, puffing up, poor appetite, and ruffled feather. Corid or amprollium in the water for 5-7 days will treat that. Worms could also be the problem, and for chickens I would recommend Valbazen or SafeGuard Liquid Goat Wormer used once and again in 10 days. For difficult worms, SafeGuard may need to be used 3-5 days in a row. Enteritis is another intestinal infection that responds to certain antibiotics such as Tylan, amoxicillin, penicillin, Gallimycin, and chlortetracycline. Offer her electrolyte water until she starts on medicines, and make sure she is drinking.
