Anatomy and Physiology of a Chicken.

If you don’t know a comb from a wattle these diagrams should quickly help you become an expert.

 

 

 

Chicken Digestive System  Chickens, as with most birds, use their beaks to pick up food and as they have no teeth they are unable to chew their food.

 

Chicken combs- types and purpose   A chicken comb is the fleshy protuberance on top of the head of a chicken, it is of course larger on the cockerel than the hen chicken.

 

Egg Formation An egg is formed gradually over a period of about 25 hours, with many organs and systems helping to convert raw materials from the food eaten by the bird into the various substances that become part of the egg.

 

Poultry Egg Fertilisation and First Hours of Development  Fertilisation of the ova (yolk) by the sperm takes place in the infundibulum about 15 minutes after its holding sac ruptures and releases it.
