A broody hen

One of our chickies has gone broody, the guy we got the eggs from in the spring gave us 15 more eggs as it is apparently the end of the fertilised egg season (they don't keep so well when it is hot I suppose).
We couldn't really put as many as 15 under her so we have put 8 some in the incubator and 7 under her.
After a couple of days of sitting we found the eggs uncovered and a bit cool. The other chickens push her off the eggs so they can lay in the nest box.
On the optimistic assumption that the eggs were growing, and that they survived being a bit cold, we have repaired a fallie apart hen house that someone gave us so she can sit on her own and not be disturbed.
