Raw chicken snack

Well at the grocery store I got a rock cornish game hen for Leopalorn again,(this time its all for him, I'm fed up with eating chicken personaly, had one a few days ago) He ate almost 2 wings total! Ripping the meat off the wing and crunching bone and everything. I'm gonna give him the rest over the next few days ( anyone on here know how long can a raw chicken safely be left in the fridge once its been removed from its package?)

I gave him some Natures varity Chicken turkey madallons too

2-3 days when stored in the fridge

Do you feed the chicken skin or take it off first? (Im going to try raw soon so just curious!)

I strip it off and give it all to him, The bones I keep unless they are small
