A newly adopted bun is not eating normally, can it be stress related?

[Happy Hopping]

So I just adopted a bun, arrived last night, it's been 24 hr. The rabbit rescue told me he's a very shy / nervous rabbit. When he first arrive, he sits at the litter tray, not moving at all, for a few hr. So about 3 hr. later, the rabbit rescue told me to give him a cardboard box to resemble a cave to hide. As soon as that box is landed in the pen, he hides inside.

As recent as the day of the adoption, the rabbit rescue told me he's eating hay. But in the past 24 hr., I didn't see him eating hay. As to veggies, there is 1 coin of banana, 3 piece of organic carrot leave + 2 piece of carrot. He did consume them last night, but slowly. He also eat a little bit of pellet, again, not aggressively. The other 2 buns that I have upstair, they clean out the pellet like there is no tomorrow.

So there are rabbit poo and he does urinate, everything is normal except the poo level is just say 40 pieces this morning. It is almost like he's recovering from a GI stasis except there is no GI stasis.

So the question is, for a shy / nervous rabbit who is currently hiding in his "cave", can this new adjustment to my new environment affects his diet?

Pearl Grey would only eat when I was not in the room when she first arrived. I put a blanket over part of the area and she will happily eat in there, now is about 2 weeks later and she will eat hay in front of me but I have never seen her eat pellets or greens.

Rabbits are prey animals, live underground and are very prone to suffer in stressful situations. Any newly rehomed animal will be stressed and needs to be provided with the things they are used to and feel safest with - so somewhere to hide, no obvious stressful situations (like other animals, a lot of handling by starngers, etc), and a diet and routine that matches as fas as possible what they had before.

I would give more hiding places - maybe a tunnel - and keep the food to what they had before. Just leave them in peace for a few days while keeping an eye on them. Poo output is critical but is an good indicator of what they are eating. Don't make any sudden major changes - they need to get used to everything that has already changed in their life.

I have adopted rabbits since 2007. Prior to that, I have rabbits from 1998 to 2007, but I mistakenly bought those from breeder. From 2007 to now, all the rabbits are adopted, among them, the above bun's brother Bucky. There is no other rabbits that needs to hide in a box (resemble a cave). This is the first time

In the past 2 days, his poo output is quite good, color is good too. But he doesn't eat food given to him right away. The food can sit there for hours before he eats it. It could be pellet or veggies or 1 coin of banana. If it were any other rabbits, I would think it's a dental or mild GI stasis. But w/ this bun, he does eat them eventually. W/ no prior history on this bun, I don't know what to do

I don't think he's still stress, as today, he start chewing on the cardboard box
