Yeah totally fine  

It works on a bigger the bird the longer you hang them basis, so light birds don't really need it anyway. 
For lighter birds I normally skin them and take the breasts and legs, takes about 2 mins a bird. 
Only downside is you don't get the nice crispy skin  

I find bigger birds much easier to draw, big hands small birds are a bit of a pain. 
How are your LS and IG X LS starting to feel I know there putting weight on nicely but are they feeling meaty ?
