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.
Semi-confinement duck housing is similar to the above in many respects with the exception that ducks over 2-3 weeks of age are allowed outdoors during the day. Ducks over 4 weeks of age may spend much of their time outdoors with minimal use of shelter.
