The custom used to be to feed the birds on Shabbos, but in more recent years it became more common to feed the birds on Friday, due to a concern regarding the halacha of not feeding wild animals on Shabbos.
Anyways, if it is too difficult for you to gather some crumbs and pieces of challa to throw to the birds, you can now purchase a pre-prepared set of crumbs for the birds...
I'll assume the hechsher is on the bottom of the container, otherwise this might be a terrible michshol..
this goes up there with the jars of salt water for the seder and with the packages of 10 pieces of bread for bedikas chametz..
