It is 50 to 60 degrees outside durring the day and 28-32 degrees at nite right now. I have heat lamps for the coup and plastic over the door and windows (with a small gap at the bottom for ventilation). I will also be filling the coup with straw. I am also worried about when to put out my bantams. they are 7-1/2 weeks old but so tiny. Any suggestions would be apreciated. Thanks!!!
