My two 10 week old BO are outside tonight for the first time! The DH started working on the coop for them..it is a smaller coop and once they grow out if it and go with the ladies for good, my other 6 chicks will use it. I was hoping the DH would not get it done today...and it is calling for rain tomorrow...and he works all week....so I was thinking I had another week of them being inside. They are fully feathered..lots of feathers. I know they will be fine..I did not put any heat on them...but lots of shavings and if I find it to be too cold later..I will bring them in! I just hated closing that door on them...the two of them are so attached to me and the sound they made once the door was closed...broke my heart!! I know they will be ok...they will..but I am not so sure I will be able to sleep at all! The temps at night get to to be around 30 degrees..calling for a little warmer tonight...but I just worry they will not be warm enough...ugg!!
