How old are your kids and what do they do for chores? Do you use a chore chart / do they get an allowance or rewards?

I'd like to create a chore chart for my 6 and 4 year olds so just interested in what others do.
DS's current chore is feeding our chickens and gathering eggs but he keeps skipping the feeding/watering them part and I'm struggling with getting him to see the importance in that!
DD's job is to feed our bunny.
I'd also like to get them cleaning their own rooms and helping inside more... TIA!
