Small poop

[Smidgeyy]

So one of my chins has been having smaller poops lately.
He's eating, drinking and peeing all normally. His behavior has not changed, nor has his weight. I thought that it might have been from giving him too many 50/50 alfalfa Timothy cubes, so I thought nothing of it. None of his habits have changed aside from his poop, and I know he's eating fine since I measure his food.

The only change was switching over to Manna Pro Pro. Both chins were on Sho but I found that the bags at my local TSC were not the freshest and with only two chins, I hardly made a dent in it so a lot went to waste. I changed their food slowly a few months ago, so I'm assuming food isn't the issue.

He has not chewed nor ingested anything out of the norm. All he has to chew are apple twigs, mulberry twigs, and pumice. Treat wise, he only gets a piece of crushed rosehip per night. He gets bottled water as well.

What are your thoughts?
Should I be concerned? If so, what should I do?
I would like to avoid bringing him to the vet unless I have to. Should I get a fecal done?

Besides the poop being smaller, is it harder? If you break it open what is the consistency? Here's something that might help with examining the feces. Scroll down about 2/3 of the way: http://www.chinchillachronicles.com/chinchilla_examination.html

The poop is solid on the inside, completely healthy. I checked a few different sizes to be sure and they all appear fine. They were a bit hard, but they were likely just poops from yesterday.

Some are close to normal size for him, others are smaller. My other chins poop is about the size that he is pooping now... It's been this way for him since I got him. This one has always had larger poop in comparison.

Put the chin in the bath tub and leave it there for 15-20 min, look at the poo. If its normal shaped and sized I would not worry about it, just my opinion.

My bathtub has these no slip sticker things on the bottom... They've been there since I moved in so I'm not sure if that would be a suitable idea.

Should I lay some fleece down and give it a go? Should I provide him with anything to eat so help stimulate him to poop?

I mean they kind of appear like this photo but it's just unusual for him. His poops have been considerably larger pretty much since I got him. There are more like the small one in the middle but there are also ones the size of the others as well. Looking at my other chins poop(which has always been tiny), it doesn't appear odd. It's just concerning me since he always had larger poops.

My bathtub is wet so I'll let it dry, and put him in there after I get home from work.
