to the BYC and I know you are not actually new bc you have 53 posts but since you are having NEW Chicks arriving soon I thought you would totally understand
Week 1 85* to 90* degrees whatever is the most comfortable for the kids. The way to tell is they are huddling up under the light in a group they are huddling bc they are cold and the temp lamp (RED Heat Lamp) needs to be moved closer to increase the heat for them to break up the huddle. If they are around the outside of the light and in a circle around it it is to hot and the heat lamp need to be moved high to lower or reduce the temperature in the brooder.
Week 2 80* to 85* degrees same as above
Week 3 75* to 80 and you can see that I am lowering the temp by only 5* degrees each week
week 4 the same and so on until week 5 when you start to bring the kids outside during the days in a 360 covered pen so they are not picked off by birds of pray or have local predators get to them while your not looking
Then you will continue until the end of week 7 and they are fully feathered and absolutely no heat is needed ever again
VERY IMPORTANT. I DID NOT SEE A THERMOMETER IN THE BROODER AT ALL!!!!!!
Medicated chick feed to develop the birds without Cocci Disease and practice safe disease prevention
Vitamins in the water is healthy for the birds always. Great luck to you with your new kids.
