My chicks have been hatching since yesterday and there seems to be a chick that isn't ready yet. I have candled it several times to make sure that there is a live chick inside. Judging by the size of the chick inside it really doesn't seem that it is big enough yet though, seems to be around the 2 week size. I was thinking that when my broody hen left the nest to eat maybe another hen layed an egg. Or maybe my 5 year old put an egg under our broody. I caught her doing that 4 days ago. So my question is, will my broody lay on this egg until it hatches or should I just finish it in the incubator.
