With the broody hen, Goldie henceforth: she has four eggs left, we candled them and two are definitely going, the other two we'll check back on. There was a bit of a mess - somehow she ended up with 8 eggs, including a training egg from another nesting box. Yesterday there were two eggs on the coop floor and the wrong chicken was sitting the box. This hen has been causing issues and perhaps pecking on her while she nested. The offensive hen, PC (short for "Princess Chicken", a title she got back when she was picked on to the point of a bleeding comb, since then she's been picking on younger hens) has been moved to the basement hospital because she's been dropping shelless eggs and we've been wanting to give her a week of calcium pills.
Our attempt to move her to an external nesting box failed and resulted in her destroying one of the eggs. We might just let her hatch them in the coop, no one else bothers her and all the roosters are respectful when she puffs up.
