Domestic chickens in your yard — do they need designation before Yom Tov?
H5: Ducks, chickens, and doves kept at home are always muchan (prepared). You always intend to eat them eventually. Dovecote pigeons need designation because they're semi-wild.
Question 2
A gentile brings you fresh fish on Yom Tov morning. Can you eat them?
H10: The test is whether similar items exist locally. If yes: the fish could have been caught before Yom Tov — permitted. If no: you must wait until enough time would have passed post-Yom Tov to catch them.
Question 3
Branches fall from a palm tree on Yom Tov. Can you use them as firewood?
H11: Nolad — the branches acquired a new status by falling. Before they fell, they were part of a living tree (not designated fuel). Their new identity as "firewood" was created on Yom Tov itself.
Question 4
An animal dies on Yom Tov. When can you cut it up for dog food?
H16: If the animal was very ill before the holiday, you mentally anticipated its death — that anticipation constitutes "preparation." If it died unexpectedly, it's muktzeh.
Question 5
Fish in a large pond need to be _____ before Yom Tov to be eaten on the holiday.
H7: Fish in large ponds are hard to catch. Mere designation isn't enough — they must be actually caught and set aside before Yom Tov. This is stricter than home poultry.
