Yes
lol, so you would pay thousands of dollars for a machine, when you can gather grass for 4 rabbits by hand in 10 minutes?
Yeah, I guess 10 minutes of work a day is too much. Better pay thousands of dollars to avoid that.
before machines the only time humans fed livestock
No, thats just your imagination.
People mowed grass, gave it to animals or made hay from it and fed it to animals.
Thats what people do when pasture isnt available or when they have limited pasture and want to make the most of it.
A rabbit is 583 calories, you need to eat four rabbits a day to avoid starvation
4 rabbits a day? So you eat over 2000 calories a day? Well, I guess now we know that you are overweight.
It takes 10 weeks (70 days) for a rabbit to grow to slaughter size.
Yeah, its a miracle, although people tend to eat them even sooner, but I guess this is one of those cases where google is your enemy. Every animal has best "slaughter size" and time to reach it. It doesnt mean its mandatory to slaughter them at that time lol
If you could perfectly time births (which you cant') that would mean on any given day you would need the rabbits for the next 70 days alive in your hutch.
I dont see what confuses you there. Maybe you think its one rabbit every 70 days? Or you think that 70 days waiting is mandatory to have infinite food after that? Well, neither is true.
That's 280 rabbits at any given time
No, you dont need to wait 70 days to kill a rabbit, even tho google might have told you that.
Rabbit produces 5 rabbits every 30 to 60 days. So 10 female rabbits would give you 50 rabbits in a month or two.
Now, if you want to be overweight, I guess you can have 5 rabbits a day by having 40 female rabbits which will produce 200 rabbits in a month or two, so thats about 5 rabbits per day for you.
But no, I dont see why would you have 280 rabbits all the time, as rabbits dont give birth once a year but many times a year. So by the time you would eat 280 rabbits, you would already have another 400 which would be too much.
As for chickens being number 1, or cows being better than rabbit, you of course wouldnt know that cow eats much more than a rabbit does, and only gives birth once a year which means you wouldnt have fresh meat all the time like you do with rabbits.
As for chickens, egg is 100 calories at best, so you would need 20 eggs per day which is 40 chickens.
Having 40 rabbits is easier than having 40 chickens, since chickens raised on pasture dont give as many eggs as those fed by chicken feed, and chicken feed isnt exactly free. Plus, chickens in winter dont even produce eggs or produce just few.
And chickens for meat arent really that great, since if you want them for meat, you cant take all the eggs, and you also must wait a lot because not only does chicken lay on eggs for a long time, but baby chicks need time to grow as well.
