When can I shut the brooder off? The ducks and chicks are starting to feather out but are far from complete. The brooder has been in our room. It is time for them to go the shed. They are just too loud at night. It is going to be in the 70's-80's and 60's at night all week. I am afraid of them getting too hot/cold. Especially now that I won't have eys on them all the time anymore. Any suggestions would be great! Thanks!
