I've been doing vermicomposting long before i got chickens (i'm impatient and regular compost takes too long for me). i personally use earthworms for my chicken poo, and i usually only feed those particular worms chicken poo and carbon (lots of carbon since manure is hot) as i've found that if they are given too many other food options they'll neglect the poo. i've found they fair better in the hotter manure compost than the redworms do (the reds are the best for garden and kitchen scraps, they seem to be much more efficient than the earthworms, the chickens seem to prefer eating the reds too plus i'd feel weird feeding earthworms that mostly eat poo back the the animals the poo came from [and i need as many as possible to take care of all that poo]). i've also read a handful of articles that stated the earthworms do a better job of destroying potentially harmful bacteria in the poo which is important for me because i like to grow a lot of root crops. just my thoughts and experience, hope it helps someone.
oh, i'm not really sure how good the pine shavings would be in qauntity, the acidity might bother the worms. i would include another more plentiful source of more neutral carbon just to be safe, or maybe use aspen bedding instead of pine. it seems people are fairly opinionated on types of shavings that they use. personally, i use sand and sift it frequently. i tried cut straw for a while and it was quickly all over the place where i didnt want it and in the water and food, so i never even considered shaving since i can only assume the same thing would happen but worse... thats just me though, to each their own, do whatever works best for you.
