Looks pretty normal poop, it can look a little different depending on what they eat, and a stress poop can look wetter .
A perfect pop the fecal matter would be a little thicker and more clumped together in a more ball plop form. But this isn't concerning to me.
Do use a digital kitchen scale and a habit if weight checks once a week after morning poop. As most burds start dropping weight if they have a health issue. 3-5% of weight loss see a vet, 5% or greater burd is sick see a very quickly, and try and offer more food possible support feed baby burd formula. Since k burds burn a lot of calories. I'd have a k and h bird warmer on hand, as warmth fir sick burds us so important. And it's great to have so they can cuddle up if they need or want.
As fir cage, looks great, offer another high perch on the opposite side he us now, most burds prefer to perch higher most of the time, but it's good to try and get them to use as much of the cage as possible.
Don't forget you can put perches on the outside and top and that can be part if his play gym when out
