Hello and welcome,
My conrues are a different type, but on the baths, none of them really like it if I spray them, or get
them wet, forcefully. How ever usually in the mornings, they will bathe on their own, and quite eagerly if and when they want to, not when I try to make them take a bath, so I don't even try, I just make sure the have a medium sized , not very deep bowl with water, that they can easily climb in and out of.
On some occasions, when I splashed a little water on one, it had triggered him to start dipping his head in, and then finally just climbing into the bowl,splashing around, going in and out of the bowl, when one starts, the others all ways follow,.. since I have 4 , sometimes I need to add more water. When they are done, I change the water, put fresh water in the bowl because they also use the same to drink on occasion, even though they do have other water containers that are to small
to bathe, and intended for drinking.
Usually though for drinking, they prefer the container that are up higher, close to their perches.
The water for bathing is down at the bottom,and usually that is what they use it for. I any event
I make sure it is clean, and check it various times daily.
I never try to force them to take a bath, I wouldn't/don't like that myself, if and when somebody says I have to take a bath, and right now,.... when I was a kid this was all ways a issue , not that I never take a bath, but I like to do that when I feel like it, not when somebody says I have to.
You might find that if you have the bird with you, and you are washing your face, hands,... let the bird be on a towel, with a bowl they can bathe in, maybe splash a little water on him, and then splash some water on your face, etc. It might kind of "inspire" him to do the same, in his bowl ,...
The water should not be cold, nor hot, mine seem to like room temperature best, of course
for us "room temperature", in warm weather is really warm, obviously in a air-conditioned , environment room temperature might be kind of cold.
Other then apples, mine are not really very fond of fresh fruit, they love apples, so I not only give them some pieces of apple almost daily, but use that as a treat as well. I am not sure about pretzles nor animal crackers, we don't have those here.
Corn tortillas, are a good treat, at least mine like pieces of soft tortilla, they like broccoli and peas, but not very much (I mean amount), that is to say, at first they are very eager, and seem to
like it, but never eat very much. So I just give them small amounts,...
Lettuce, mine like, but it is not all ways available, what all my parrots seem to really love is fresh green grass, and clover, I am not sure what kind of grass it is, we have t 2 major types,..also they
like other legumes, like alfalfa, they love pieces of palm leaves, and also the leaves and branches from the mesquite trees, We don't have pellets available here , so I don't know on that.
Oddly enough, one time when I went to the US, I did bring back a large bag of a mix that I bought at a pet store, supposedly for conrues, it was a mix of seeds and dried fruits, and stuff,..
Hah, what a joke, mine did not really like most of it, they picked out the sunflower seeds and peanuts, but most of the rest they would not eat either.
I am not any nutrition expert or anything, so maybe someone else will have some other ideas , better on that. You really can not force them to eat anything they don't want to eat though.
If he is happy with a dried fruit and seed pellet mixture, it should be enough, and then maybe sometimes it will like a piece of carrot or lettuce, occasionally, for a change.
They do seem to get bored, just like we do, with the same old thing every day,... "Oh no, not this again",..
