apparently a large portion of the krill fleet is only hours from striking earth.
The Krill come at Warp from their own space (which as far as I know is next to Union space as the closest non-ally territory), as that is where Grayson and Gordon go to get them in the shuttle. We don't know the time it took them to come, but a few hours at warp seems fine to me to get to earth from their own space.

Earth is nevertheless apparently only lightly defended.
It's defended well enough, but the fleet is recalled because this is the Kaylon...a species who they fear more than even the Krill, because they know so little about them and know how xenophobic they are. The Admiral is being cautious.

Apparently the union would need weeks to recall the whole fleet.
The fleet is spread across the entire galaxy, far flung places could be weeks out even at warp.

Kaylon is also apparently only hours from earth.
I'm not sure where you get this information to be honest. We are given no timeframe from when the Kaylon steal the Orville and leave their homeworld till they reach earth...Earth only gets word WELL into the journey when Yafit and Ty send the message. So it could be weeks and we don't know.
