afhankelijk van eventuele ziekte (denk aan bacteriele infectie of zo waar er uberhaupt niets aan te doen is) is het wel mogelijk een zwak kuiken met success groot te brengen ... (ja ja ik weet het>dit valt niet goeds in het keel van veel mensen maar ik ging vanuit dit persoon heeft deze dieren als "pets" en dan niet voor fok of kleine schalig productie doeleinden) en dan is temperatuur van uitermate belang de eerste drie weken wil je uberhaupt kans van success hebben (nogmaals ik geef hieraan dat het mogelijk is maar als het niet lukt dan moet je niet verbaasd zijn> de ene keer lukt het we de ander niet en dan moet je ook realizeren dan dat deze kuiken zal waarschijnelijk altijd een ietsje minder waardig afweersysteem hebben dan de anderen en daar even rekening mee houden in uw zorg) In het volgende article leggen ze uit hoe en waarom een constant temperatuur en de
juiste temperatuur de eerste drie weken zo zeer van belang is voor de kuiken dat je zelf groot brengt (want je moet het niet de eerste weken terug leggen bij de rest of onder de moeder want dat zal de dood betekenen>zwakheid word niet getoloreerd en ze maken deze zwakkelingen meestal snel af):

"Research has shown that the chick develops the ability to regulate its body temperature around 12 to 14 days of age. The chick can be easily stressed if its body temperature decreases or increases by as much as one degree. Once the body temperature changes the bird will try to compensate and it most cases this means that it will have a negative effect on performance. The body temperature of a day-old chick is approximately 103 degrees F (39 degrees C), but by about five days of age body temperature is 106 degrees F (41.1 degrees C), the same as the adult. Extreme temperatures (high or low) often result in chick mortality,
but even mild chilling or overheating can damage young chicks without causing death. While chicks are more tolerant of high temperatures than adult birds, high temperatures for extended periods of time increase mortality and have negative impact on performance.
Research has shown chicks that are subjected to cold temperature have impaired immune and digestive systems. As a result,
cold stressed chicks have reduced growth and increased susceptibility to diseases. Cold stressed chicks will exhibit higher incidence of ascites, a metabolic disorder that results in reduced performance, increased mortality and increased condemnations at the processing plant. In research studies where groups of chicks were brooded at either 80 degrees F or 90 degrees F,
the chicks reared under the warmer temperature had better weight gains, feed conversion and livability. Chicks brooded under 80 degrees F experienced reduced growth compared to the high brooding temperature treatment. The chicks reared under those temperatures did not catch up in body weight and as a result weighed less at market age than birds that were brooded properly. Not only do chicks exposed to low brooding temperatures have reduce growth rates, but they will consume more feed to keep themselves warm, reducing feed efficiency and increasing feed costs.
Temperature and Chick Environment
One of the goals during brooding is to maintain chicks within their comfort zone, which is where they are not using energy to gain or loose heat to maintain body temperature.
When birds are kept in environmental temperatures above or below their comfort zone, more energy must be expended to maintain body temperature. This extra energy will ultimately be supplied by the feed consumed. Therefore, the energy from the feed will be used to maintain body temperature instead of growth and development resulting in poorer feed conversion...."
