how to grow and maintain herbs on a window sill garden?

live in a flat where only sunny window sill also share space with numerous pigeons. but i love to cook with fresh herbs, like oregano, thyme, rosemary, coriander, parsley, etc. can anyone give me tips on how to do this on a window sill garden? is it really bad if they get the occassional pigeon poop? i would know how to keep them pesky pigeons away from the plants.

Pigeon poop transmit over 60 diseases. You don't want it anywhere near your edibles.If you can't prevent them from coming near, grow your herbs inside, facing a southern window, or hanging from baskets
