Thank you! Always learning here too. I've got 3 different water additives in her water trough right now for tonight. She's had one portion of force feeding at the vet, they say it's good for 8 hrs, so if she's not eating tomorrow morning, she gets another one. They taught me to put the tube down her right side of the neck, until it gently bumps the bottom of the crop. Then slowly pump the syringe of food down. It takes 2 people.
The water additives I've put in her water are Rooster Booster, Wellness Brew (for poultry, has a variety of herbs etc), and apple cider vinegar. I need to start adding a niacin supplement as well, soon.
We had the option for an xray, we were open to the idea, but I discussed it with my mate, and we didn't want to do it if it was unnecessary. If she doesn't start to get better, we can take her back. They did a fecal test, it was clear. We were given goose antibiotics to only give her if necessary as well. Put that in the cabinet, just in case for the future. My mate is convinced her behavior is phycological, perhaps it is. All we can do is give her some time and go from there.
During the day on days we are off work, she gets locked out from the cage and 'free range' to grass in the backyard.
