Ok a really good way to make money while leveling your low cb stats is to kill chickens now.
I mean there is probably already another chicken killing guide, but because of the recent runescape updates most bots now do not work.
And because they don't work prices of everything have gone up so much. feathers are worth 16gp each! as opposed to 5gp.
from 1-20 attack i made about 50k and it only took me 1 hour tops
So get chicken killing it is worth it.
