Okay so 3 days ago our Swedish duck became broody and we gave her 7 eggs to set on. I just went in and checked on her and she is still sitting. I lifted her up a bit and felt the eggs... they are cold??? I know for sure she has been sitting continuously only getting feed in the morning and then going back. I am confused as to why they are cold. None of them stick out, she covers them all. Any ideas?
