Big farm upgrade costs you 30000 Coins and 1 hour build time
Don’t focus feed one of your animal, the increases in coins generated are not worth the cost. Feed all of your animals to level 5-7 first, because on those level ranges they only require a minimum amount of food. After you have feed them all to level 7, then progress to level 10, at this time I believe you have upgraded your farm to the big farm, which provide you an access into better food.
Feed the rarer animal first!! It seems they take too much food but their income increased per level is more efficient than normal rarity animal.
I said don’t focus feed, but when you already have many lvl 10 animals (to generate constant coins), stop there. Focus feed the super rare creature that you have to lvl 15, so you have a better chance to win the battle tournament.

From the chart, it’s clear that the most effective food is Aura Apples; however, you need to farm it every 30 seconds, which is really tiring…. When you only have the small farm, I suggest you to farm Power Pears because it’s the most effective in terms of coins usage and time. You only need to farm 2,5 power pears to be able to get the same amount of food as Mana Bananas. 3 minutes may seems so tiring but your routine of playing game should be like
Open the game => Grow Power pears => enter battleground to spend your stamina, breed, or anything
Those steps should take about 3 minutes to complete.
I still recommend you to use power pears, when you have upgraded the farm to the big version, but if you are lazy then only use Mystic Mangos (8 hours), because it’s most efficient food from the big farm. Make sure you plant Mystic Mangos every time before you go sleep.
As you can see that the grand farm doesn’t add any longer time frame. It only means to get foods ASAP (by using a lot of money). The biggest flaw for this farm is the size, you need 4×4 space .. (before it’s a 3×3 space). Unless you have a lot of unspent coins (and empty lands), I suggest you to halt the constructions on this farm.
