Summoners War: Chronicles

The fact that you need 100 pieces of chicken for level 2 of cooking profession, and then there's literally no information ANYWHERE on where to get it other than it drops from something, somewhere, sometimes. I've spent the past 8 hours grinding killing monsters in every location, and I've gotten 35 pieces, after 8 hours. Go to the collection book? Chicken isn't even in it. Go to the locate thing in the recipe? It just says you can get it from field monsters, in every location, which is 100% false. I never thought I'd quit a game over chicken but this is stupidly frustrating.
