Typically, most breeds of chickens mature at about 6 months of age. This is when their bone structure has reached 'adult' proportions, and when hens begin to lay eggs. However, they will continue to put on weight and fill out until close to 18 months.

Broiler chickens have been bred specifically for fast growth and weight gain to supply the food market. These chickens will reach a target of five pounds in an average of 45 days. This practice has caused some concern over the sustainability of the breed, however, as due to the rapid weight gain (up to 100 grams per day, which is over five times that of a normal chicken), they are often unable to walk well, and often suffer fatal heart attacks during the period of most rapid growth.

Brutus compares Caesar to a newly hatched serpent in order to show that Caesar is?

Brutus actually compares Caesar to an unhatched serpent, not to a newly hatched one. "And therefore think him as a serpent's egg, which, hatch'd would, as his kind, grow mischievous" The point of the comparison is to show that Caesar is potentially dangerous, not dangerous now.

How do chicks begin life?

A chick needs a source of nutrition for it to grow in the egg, which can be gleaned from the yolk. Once the chick has absorbed the yolk into the abdomen, it uses its beak to start pecking at the inside of the egg to break it open so it can be hatched.

What is a new born fish called?

Are your referring to what they are called? They are called fry. Some people call them guppies but that is not right. A guppy is a species of fish, not a baby fish. Young or baby fish are usually just called fry, but some sciency types will call them larvae if it is appropriate.

Why is the egg yolk cell so big?

The yolk is a source of energy for the embryo to live off of once the egg has been laid. The embryo is actually a part of the yolk membrane, a mere little white dot on the membrane of the much larger yolk sac. Since the embryo has no external source of energy to grow from, unlike mammals grown in the womb of their mothers do, the yolk sac acts as that source of energy for the embryo and chick fetus to grow from. Fetal mammals, in comparison, have a placenta and umbilical cord that anchors that fetus to the mother, allowing the mother to give nutrients to her fetus from the external food sources she eats. The yolk is high in saturated fatty acids, protein and carbohydrates which is everything a growing chick-fetus needs to grow in the egg. A few days before the chick is hatched, the yolk sac is enveloped by the chick into the chick's abdomen. This continue to provide a source of energy for a day or two after the chick has been hatched, but is absorbed into the chick's abdominal cavity once all the energy has been used up and the chick begins to eat on its own.

Are crocodiles bigger than toads?

Depends on age. There are adult toads that are bigger by weight and volume than newly hatched crocs. But it doesn't take long for the crocs to grow bigger than even the biggest toads.

What is a baby spiders diet?

Hatchling spiders will feed on tiny insects. For example, the baby spiders in my collection feed on what are known as 'micro-crickets'. These are newly-hatched crickets about 2-3 millimetres in length. I gradually increase the size of the crickets as the spiderlings grow.
