[Histonet] soften beak

[Rui TAHARA]

Hi, 

I am just wondering what you would recommend to soften avian beak for paraffin processing. 
I found a protocol that KOH could be used to soften keratin in nail, however, I have not been able to find that this method is applicable specific to beak. 
Another concern is if i use KOH for an entire head, does KOH affect (e.g. damage) soft tissues?

Thank you in advance,
