It has a soft tush ;)
Don't be silly
Around three weeks.
so it can keep them warm.
It will sit until the others all hatch and leave any that don't hatch.
you will probably crush it. You get wet, no egg for breakfast and a smack from your mum for making extra laundry.
no because the mother will squash the egg and cause it to die
no it needs to sit on the egg or eggs for 34 days. You are partially correct -- an egg cannot sit ignored and still hatch -- but it 21 days, not 34.
It depends on the chicken. Some will sit and then gradually get more and more eggs. Chickens in all don't have a "limit" of eggs they will sit. Often a hen will go broody without sitting on any eggs. Some hens have sat on twenty eggs but it can be hard for them. Sometimes one egg. But on average and for an average chicken, it would be around a dozen.
Have chicken mama sit on the egg. Mine hatched in about a minute ^_^ Toss egg in the air and you will see another crack Rock egg back and forth and he should hatch
you turn into a chicken and sit on it for warmth.
balance the chiken on your helmet and sit on the cow
The actual formation of the egg inside the chicken takes about 24 hours, but when they sit down to lay the egg it can take anywhere from 15 minutes to a couple of hours.
