Small poop

Sorry another question... For those who don’t know Pepper has been shedding for the first time and with adivce from here i have it under control now. Im not sure though now about his poop. They are smaller than usual... he is acting normally and eating alot of hay (as advice per shedding) and i am curious if it could be too many pellets or too many veggies?
The smaller ones are on the bottom left side and the upper right are alittle more normal. Thank you! Just a bit paranoid.
