I took my 4 week old ducks out to play with older ducks and as I am trying to catch them they want to stay in the big coop and run. Will it hurt for them to stay outside? They haven't wanted a heat lamp in over a week. It's not that bad outside during the day but in the 30's and 40's at night. We completely covered both run and coop to keep out any drafts tonight. My daughter would just kill me if anything happened to them. When hubby gets home I could have him climb in there to catch them if I have to. Thanks for your help.
