Slow digestion causes bacterial enteritis. Coccidiosis and intestinal worms can also cause enteritis, and prolonged presence in the intestines causes irreversible damage. Don't feed rice or too high protein for right now. A chicken drinking less in cold weather will cause dehydration, especially when electrolytes and vitamins are not regularly supplemented in water ( 3 days a week ). After a regiment of antibiotics, gut flora is disrupted so it is highly beneficial to supplement probiotic dispersible powder for a day or two the first few days after the last antibiotic treatment, and once a week on a regular basis. Lactobacillus prevents pathogenic gram-negative bacteria from colonizing the gastrointestinal tract. In the case of your bird, give food stuffs that are easy to digest ( buttermilk soaked bread in small amounts, warm water moistened crumbles/pellets, and withhold scratch grains for right now.). Make sure the crop is emptying properly. It should be empty in the morning before feeding.
Tylan is not a good solution to bacterial enteritis and is generally used for respiratory infections. Neomycin, Lincomycin-Spectinomycin (L-S 50), are often used to beat bacterial enteritis. Both can often be found at local feed stores and require 1 tsp per gallon of water for 5 days with Neomycin powder, and 2 grams (about 1 tsp) per gallon of water for 5-7 days with L-S 50. Like all water solubles, the bird must be drinking on its own to benefit from the treatment.
Hydrate the bird first by supplying vitamins-electrolytes labeled for poultry for 2 days, and for one of those days add a water dispersible probiotic like Probios at 1 tsp per gallon of water. Feed what I mentioned and see if there's improvement in 2 -3 days. Depending on whether your birds were dewormed with the proper dosage of Valbazen (Albendazole), and the length of time since the last dose in your particular environment they live in, determines whether or not intestinal worms, or even coccidiosis could be the culprit for intestinal problems. I supplement all year long and rarely see problems, but Winter and Spring/ humidity can provide an environment for nasty microorganisms, endo/ectoparasite populations and their vectors to increase. That is why a strong immune system is important.
