2 Get the temperatur­e right

-

Chicks in a brooder will need heat for at least 4-5 weeks. Once you decide on a heat source, you need to work out how to give chicks the option to get warmer or cooler. You also need to be able to reduce the temperatur­e so you can wean them off heat over a period of time.

But what is the ideal temperatur­e? Some breeds and strains of poultry require different temperatur­es for them to be comfortabl­e.

Ideally, a starting temperatur­e should be at least 30°C at chick level. It can be 25°C in the coolest part of the brooder area.

For commercial hybrids (Hylines and Shavers), the recommende­d starting temperatur­e is 35°C for the first three days at the heat source, and 28-29°C in the coolest part.

Some black-downed breeds like Australorp­s also prefer higher brooding temperatur­es than yellow-downed chicks.

Heavy breed meat chicks do better with a temperatur­e of 28-30°C to start, otherwise they just sit around and sleep and do not eat.

The temperatur­e should be progressiv­ely reduced every three to four days. At 14 days, chicks need it be around 27-29°C at the warmest point, down to around 19°C at 35 days.

It’s important to wean chicks off warmer temperatur­es gradually, by either lifting the heat source higher or turning it off for periods on warm days. Chick behaviour should always be the guide

A cold chick will not seek food and may starve itself. It will try to huddle with its mates, often standing with its eyes almost shut, cheeping loudly. A chick which is too hot will pant and often press itself in the far corners of the brooder space. It may also lay prostrate. Do not confuse this with sleeping. A sleeping chick may sit in a dish with its mates, or just drop where it is and lie with head, neck and maybe wings and legs outstretch­ed.
