Today is really windy and 73 here. I have had my BO chicks (4 1/2 wks old) outside in their run before. They were in their brooder raising a ruckus cause they wanted out so I took them out and put them inside their coop with the door closed due to the winds (10-20mph). Is this ok? I have only had them outside when it is calm and above 70. They have most of their feathers and just love it outside. I put food and water in the coop for them. This is their first time in the coop due to me just getting it finished. I bring them in at night since it still gets down into the low 40s. Am I doing this correctly? At what temp is it ok to leave them outside overnight? Or age? I will add a pic of them so you can see how feathered they are. I have all the vents open and the windows on the no wind side open completely. Tomorrow will be 84 and windy & then Friday back to 66/48 so trying to figure out what to do. Thank you for any input.
