Does anyone know the longest you can give a chicken penicllin? I heared 7 days is the max you can give safely but my hen Hanna still has egg yolk in her stool and is still bloated. She seems to be eating better after giving her the injections and is able to sit down now ( could only stand before injections) but I don't think the infection is gone because of all the egg yolk in her stool, so maybe I should reduce the dosage to 1/4 cc for maybe 3 more days max just to make sure she gets rid of the infection. Does that sound okay? I've also been give her probios a few hours after injections to put the good bacteria back in her body and also have been putting organic apple cider vineagar in her water everyday.
You can do a water/vinegar flush to prevent bacterial infection.
Use a large syringe without a needle, mixing 1 tablespoon of WHITE vinegar to 1 quart of water. Use a full syringe of the mixture and insert the syringe into her vent and flush....like a douche. Use about 3 or 4 syringefuls, the liquid may or may not flow of her vent afterwards.
Honestly, the outlook doesnt look good for your hen and will most likely be an ongoing situation. I recommend that you cull her.
