I'm not a minecraft veteran by any means, although I've been playing the game for quite some time now.I recently came to realize that there aren't many farming bocks in minecraft . There are only 3 to be specific:
1.Farming Block (Using a Hoe on a dirt block.)
2.Composter(Gives the profession 'Farmer' to a villager. Also helpful in making bone meal.) &
3.Hay bales (can be crafted using a crafting table using 9 wheat ;can be placed as a physical block.)
P.S. Apologies, If I'm missing something out.
I, however have a suggestion for a new category of farming blocks. The blocks being:
1.Cow/Sheep feeder (feeders for cow/ sheep that give wheat when a cow/sheep is in the mood to eat.)
2.Trough(Throff) (feeds carrots pigs when they are in the mood to eat. )
3.Chicken feeder (feeds wheat seeds, melon seeds and/or pumpkin seeds to chicken when they ae in the mood to eat.)
That's about all the blocks I could come up with. However, I personally think that these blocks could be seriously helpful for a player in a new survival/hardcore world, as he will have to spend less time breeding the animals manually and just put the correct food items in the designated feeders.
Might I suggest an all purpose trough instead? The Quark Mod adds a Trough Block that can be filled with seeds, wheat, or other useable foodstuffs either by a player or a hopper in order to breed animals automatically. For balancing, using a feeding trough to breed animals only works about a third of tie time, making it more efficient to breed by hand. (Incidentally, Quark also adds compacted block versions of other foods, such as basket blocks of carrots and apples.)
I would say this: I for one like this idea, and think automatic farming ought to be a thing- or at the very least a bit less nonsensical, seeing as the current ideal for farming meat literally consists of dumping a bunch of cows in a hole until they aphyxiate. An automatic feeding trough would encourage new designs of auto farms, and I for one don't think it would be overpowered. (Especially given how effective the whole cow thing is.)
