Meningitis in Adults Quick Overview. Meningitis is a potentially life-threatening infection of the meninges, the tough layer of tissue that surrounds the brain and the spinal cord. If not treated, meningitis can lead to brain swelling and cause permanent disability, coma, and even death.
i moved my 3 ducks outside at 2 weeks for the same reason. we didnt use a heat lamp but they are housed with 2.5 mo old chicks to help stay warm. the temp has dropped into the low 40's and the birds have been fine outside for 2 weeks now. as long as you have the heat lamp they should be fine.
Ducks can go outside really early. This I put my ducks out around 3 and 4 weeks old at the end of feb/ early march. I usually prep them by shutting their heat lamp off at night around 2 weeks and then not having the heat lamp on at all a few days after that. They adapt to it really quickly.
