is there a walkthrough?

i tried feeding the tribe and dragged each tribe member over to the storage bin and clicked on the food needed... each was fed but the task is not complete. what am i doing wrong?

All of them have to be full in addition to being fed, so if you are taking too long your first fed might be not full by the time you finish the last, So make sure you have plenty of food, feed them quickly, and drag them often until you get it.

There is a walkthrough or a list of each task with some hints on the walkthrough page here. It is the response to the last question.
