I was in a similar situation like you a few months ago. I had found an entire litter that was about 2 weeks old and bottle fed them with the kitten formula. The orange feces is normal because the kittens body had digested the formula that you had given it. As for the blood in the feces, that is sometimes normal as well. It is normal because the kitten could have not eaten for awhile and it wasn't used to going "potty." Remember though, after you feed it make sure you take a soft tissue or paper towel...or even old rag and make sure you stimulate it to make sure it does go to the bathroom.
I used baby wet wipes on my kittens after I fed them to stimulate them to go to the bathroom.
Good luck with your kitty.
