Could be a bit warm for them to germinate now. Give them time, I'm sure they'll grow. In the mean time, buy a pot of chives from the supermarket and plant those. I'm ashamed to admit but I've used s'market pots for a lot of my herb planting this year, quick and easy.If you wait 'till the plants are 'passed their sell by' date you get them for next to nothing and once in the ground rejuvinate and grow on quickly :D
