My ducklings are coming in next week and i'm planning on putting them in the garage with no heat lamp. The average high of those days will be mid to low 80's. Will that be fine for couple day old ducklings. I can give a heat lamp to them but they will have to go fully indoors. I do know the temp needs to be at least 90 for those age of ducklings. Tomorrow or Sunday I will be setting up the brooder.
