But free-range chickens can hide food, otherwise they will certainly not live if they are hungry for a month. Ducks can't survive just because they eat too much, not even if they are fed a catty at a time. Fish have strong hunger tolerance and can rely on their own fat to maintain their lives. Being hungry for a month is very scientific, because I have seen an ordinary fish. After being hungry for three months, it is still skinny. Like ducks, pigs are greedy, but they are not immortals. By the way, sloths eat almost all the time, but they don't think they can't live if they eat all day. For sloths, this can only make them full, because their food nutrition is very low, and only by eating a lot can they maintain energy supply.
