I'm gonna be making a new batch of food soon, so I was wondering--do you think I should introduce slivers and keep working on getting him to eat in the cage, or should I keep the soup the consistency it's at until he's eating in the cage independently?
Slivers would be a good idea to try at this stage, so long as he's eating a sorta decent amount when you feed him.
When you say 'a new batch', how much are you planning to make at a time? The reason I ask is because he may be ready to move reasonably fast, and you don't want to hold him back by only having slivers available if he's ready to eat chunks. What I did was I used chicken thigh in my soup recipe, and made a pretty decently big batch. I kept some of those chicken thighs whole, and cut them each day to simply add to the soup. Do slivers the first day. If he eats them, double their size the second day, and then start decreasing the soup to slivers ratio. With Ezra, I jumped from 10% chunks to 50% and then 80% chunks over the course of two days, and he never had trouble. If he eats around the chunks, just make them smaller or a lesser ratio next time.
Meanwhile, work on getting him to eat from the bowl consistently, and then from inside the cage. If you don't already, you might try hand-feeding him while he's standing inside the cage, keeping in mind the spoon-lowering trick.
Awesome, let me know how he does with slivers! Remember that the worst that could happen is you have to take a step back to smaller slivers, so don't be afraid to see how big you can make the chunks and have him still eat them.
We had a breakthrough today! I added some chopped gizzard to his soup and he ate a few of the slivers...I had to hand feed him, but still! Haha. I'll work on increasing the chunk to soup ratio and getting him to eat in the cage.
Go Remus! Now keep pushing him to do that more often, since he's getting the hang. The best thing to do is to expect at least that much from him, and push for more. Have you tried leaving the food and not feeding it by hand for a whole meal yet? If you've seen him do it, it means he knows it's food and where to find it. Give it a shot the next time you feed him, and weigh the bowl to see how much he eats when it's left in the cage. If he's hungry, he'll eat. If he doesn't eat, he'll be good and hungry the next time you feed him.
