Broody Hens

Argh! Like buses, broody hens always seem to come at once. The irony of these four hens from my breeding pen of four Indian Game hens is that if they're all broody none of them are laying any eggs! 

 Also not sure sure the nest box can take them all in there at the same time! It must get pretty warm.

With broody hens I tend to leave them pretty much alone but I do chuck them off the nest once a day, I even do this when they're sitting on eggs, as they sometimes won't look after themselves by feeding and drinking properly. Also lets them do a big poo away from the nest - which is a good way to help keep things clean. 

Anyone else have too many broody hens at the moment?
