That's a crop condition. Usually a blockage.
What is Tylan going to do for it?! Is this an avian vet and was the Tylan prescribed?
Reading the other thread.. dang, she's had lots of things thrown at her!
I'm gonna need some time to review.. but unless you lay OFF the treats and feed ONLY chicken feed or moistened chicken feed.. she will continue to be ill.. in my opinion.
Blueberries, carrots, seeds, mealworms and the like do NOT have the added vitamins, minerals, and AMINO ACIDS a formulated ration does. They are also high value foods so why settle for measly, every day, boring, chicken ration when you can fill up on the good stuff? If she eats ANY of that stuff it cannot count as decreased appetite. Can you get a weight on her? When was the last time she laid? How long has she been on the Tylan and do you understand that antibiotics often cause diarrhea?..
Can you start here again with a CLEAR and DETAILED summary of what and when from the beginning until now.. draw it together at this place to start the NEW review of the SAME illness that clearly hasn't fully resolved yet??
Please understand that I'm trying to be straight with you and not scolding or rude. I can see you are trying, hang in there!
But back it up and take it to the basics.. Cut out ALL treats.. is the crop clear in the morning now? Coccidiosis AND internal parasites have been ruled out. This salmonella.. is reaching for straws.. when the basic root of the problem was never addressed properly YET.. lets do that!
