Shabbat 128 - July 12, 20 Tamuz

The gemara goes through all the cases in the mishna regarding items in the storehouse that are considered muktze that one is not allowed to move. All of the cases seem obvious that they are muktze so what is the mishna trying to tell us? If there are food items that are worthy for animals that only rich people have, can one carry them or not? Do we view all of us as if we are like "sons of kings"? Can one carry meat that is unsalted on Shabbat? What about unsalted fish? What actions are allowed to be performed for animals if it is to prevent financial loss or prevent the animal from suffering? How can one help an animal (who is considered muktze) to return home - what type of help is allowed - pushing only or actually helping to walk? Why are the rules for hens different than for other animals/birds? What about a child? Preventing animals from suffering, tzaar baalei chayim, is a Torah law - what is the source? And because if that, is can override a rabbinic law. What can be done to help an animal giving birth on Shabbat? What can be done to help a woman giving birth? A midwife is allowed to travel from far to help with the birth? How else can one desecrate Shabbat on her behalf?
