Most cages I have DO come with grates.
I kept the grates in for the budgies, as i found they are more foraging birds, and liked to play with their poop and the newspaper... which I didn't like.
But for the tiels, i take out their grates for various reasons. 1) I found they are more clumsy, and would trip a lot while walking on grates 2) So if they have night frights, they land on softer solid floor rather than wires 3) when/if they do fall, or even for walking around on the bottom of the cage... if there was a grate i found my tiels tail feathers broke more, which sucked! lol 4) I found tiels were more clumsy and spilt more food, which would waste if they could't get to it (if there WAS a grate on). Where as without one, they can go down to get the millet the dropped, or their sun flower they dropped e.t.c.
So, i say no grates for tiels, and yes grates for budgies
