Probably not, but it should be removed.
Did you look at the link I posted?
Hopefully the carcass is now resting in the fridge for 48-72 hours before cooking(for rigor mortise to pass-or meat will be very tough).
I would cut up bird in parts(have you ever cut up a chicken before? If not...
I usually loosen and remove the crop and trachea first, then go in the back.
I withhold feed over night to clear intestines, then give a tablespoon of scratch grains 30 minutes before slaughter to make the crop a bit easier to grab and peel away.
The gizzard or the crop?
Crop is on right side of neck/chest area..can be full of feed if you don't fast them before slaughter.
Gizzard is deep inside body cavity.....thick muscle , with grit and maybe feed inside.
This tutorial shows all organs...
