The price for the first ant from a tile should be included in the amount of food i costs to place the tile.
It's a bit annoying and can seriously screw up your plans if other ants respawn in the mean time, consuming food, so the ants from the tiles you just placed cannot hatch.
This might not be an issue at the moment, but with bigger ants that cost a lot more to hatch I can see this quickly becoming a major issue.
There also should be a button to stop the queen from egg-laying entirely, for example when you need food for something else (like placing food tiles) and a list which (ant species) eggs are preferred/allowed to hatch (so if you run low on workers you could order your colony to only spawn workers, if you need more tanks you could only allow Myrmecia eggs to hatch, etc.). That would allow for much more efficient resource management.
