When I've had a problem with them eating I'll put 3 or 4 dessert spoons of veg soup on their food. Coat the food with it to give it a different taste. The next day I'd use the source from baked beans,then back to the soup. I also feed less but 3 times a day. Hopefully it gets them back on their food. A spoon full of suger helps the medicine go down so to speak. Its worked for me in the past. Hope you can work it out.
