White chicken
cost = 12,000

produce value = 240
time to produce = 6 hours

12,000 / 240 = 50 eggs to recover cost
50 x 6 = 300 hours
300 hours divide by 24 = 12.5
(if u feed them and make them happy so production time wont be affected)

therefore 12.5 days before u start making profits

Common sheep
cost = 30,000

produce value = 700
time to produce = 14 hours

30,000 / 700 = 43 wools to recover cost
43 x 14 = 602 hours
602 hours divide by 24 = 25.08
(if u feed them and make them happy so production time wont be affected)

therefore 25 days before u start making profits

Brown sheep
cost = 40,000

produce value = 840
time to produce = 14 hours

40,000 / 840 = 48 wools to recover cost
48 x 14 = 672 hours
672 hours divide by 24 = 28
(if u feed them and make them happy so production time wont be affected)

therefore 28 days before u start making profits

White cow
cost = 80,000

produce value = 2000
time to produce = 20 hours

40 milks to recover cost
40 x 20 = 800 hours
800 hours divide by 24 = 33.33
(if u feed them and make them happy so production time wont be affected)

therefore 33 days before u start making profits

This is the amount of days before u actually start earning profits
However this calculations does not include maintence cost on grass and wheat ~

Just to compare White Cow with Brown Cow:
White Cow produces 2,000 per 20 hours, and takes roughly 33.33 days for you to start turning in profit (not including the time it takes to mature), assuming you have it well brushed and fed. (about 35.83 days if you include costs for grass)

Brown cow produces 2,200 per 20 hours and you turn in profit once it mature.
Assuming a cost of 180 in grass, you will make about 79,200 – (180*30) = 73,800 in 30 days. Again, assuming it’s fully fed and happy all the time.

A chicken produces 7,200 in 30 days

A sheep produces 21,000 in 30 days
A cow produces 60,000 in 30 days

Cows are the most profitable. In about 48 days, your cow will make more than what your chicken make, and in 90 days, the profit that your cow will bring in double what a chicken is able to bring in (in that 90 days).

I hope this guide will help you.
