An ectotherm (from Ancient Greek ἐκτός (ektós) ' outside ' and θερμός (thermós) ' heat '), more commonly referred to as a "cold-blooded animal", [1] is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature.

The quantity of feed, and the nutritional requirements of the feed, depend on the weight and age of the poultry, their rate of growth, their rate of egg production, the weather (cold or wet weather causes higher energy expenditure), and the amount of nutrition the poultry obtain from foraging. This results in a wide variety of feed formulations.
However, others who keep chickens believe they are prone to illness in outdoor weather and need a controlled-environment coop. This has led to two housing designs for chickens: fresh-air houses with wide openings and nothing more than wire mesh between chickens and the weather (even in Northern winters), or closed houses with doors, windows and ...
But snakes and alligators do go into a similar state when temperatures begin to drop to help them survive the cold. Just as some warm-blooded animals hibernate during the winter as they endure ...
Cold-blooded is an informal term for one or more of a group of characteristics that determine an animal's thermophysiology. These include: Ectothermy, controlling body temperature through external processes, such as by basking in the sun; Poikilothermy, the ability of an organism to function over a wide internal temperature range
After all, chickens come with a bunch of im-peck-able perks: Fresh eggs in an assortment of beautiful colors, automatic pest control, waste that can contribute to the compost pile or fertilizer ...
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
Warm-blooded is a term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals ) maintain a stable body temperature by regulating metabolic processes.
