My newly hatched ducklings can generate quite a smell. I cant walk into my room without dry heaving first. I have a big bunny house that I can convert into an outdoor brooder. Can they be moved outside at 2 weeks of age. the temp is about 80 to 90. I live in Florida. One last question, What should I add to the brooder. I might add a ventilation system with a pc fan. Thank you for your time.
