Chickens on minecraft seem to lay eggs at random regardless of where they are standing. Chickens tend to lay eggs about every seven minutes. The best way to get eggs is to get more chickens, and then fence them in so they do not wander off.
Yes
You can breed chickens.(Only in creative mode) I don't remember the exact command but something like ( /spawn* )? I my self do not have a minecraft account my friend does i'll ask him and get back to you.
In mass amounts, they do. This applies to any mob in Minecraft, not just one. OptiFine is a mod that you can install to help cope with lag, however it is meant for slower computers, and I found it does not work too well with great computers, as I have tried previously. Surprisingly, it decreases my FPS, although that is on my personal level.
Chickens do not need to eat, but give two chickens wheat and they will have a chick. Same with cows, sheep, pigs, and mooshroms.
No they don't. They might drop feathers, but they will not eat chickens so your farm is safe.
You cannot put chickens on your head without mods or a server plugin.
You can feed chickens by right-clicking on them with wheat seeds, melon seeds, pumpkin seeds, or nether wart in hand.
They lay eggs and when killed drop feathers and raw chicken. They can be bred using seeds.
Wheat Seeds.
if thers so much it can case it to lag
You can't. That is impossible. The only way to get feathers on Minecraft is from chickens.
You should never put anything over a chickens head to begin with, so no.
Chickens can be fed seeds to make them breed.
You feed CHICKENS by right clicking them with seeds.
seeds
you get carrots in minecraft from baby zombies on chickens or spiders, you have to kill them and then you will get them.
Use eggs.
The chickens Head sits at the top of the neck. If you mean is the brain at the back of the chickens head then the answer is yes, at the back of the head just behind the eyes.
You can tame chickens in minecraft. with seeds. :) and you can tame creepers by tossing them a red flower as of 1.8 by left clicking on them.If two loving chickens meet they will breed and make a baby chicken. your welcom@!!!
Usually, a head piece will come with a full outfit, apart from that, I don't think you can buy headgear by itself.
You go up to a chicken, put your cursor (the little plus in the middle) over the chicken, and then keep on left clicking it until it dies.
Wheat, just like every other animal.
