Soft shell question, problem solved (I hope)

Thanks to all for their assistance.  Bob is now fully functional.  in the end I have put it down to food.  I tried her (well all of them) with some mash mixed in with their pellets, she seemed a lot more eager and then this morning 4 eggs!  You can actually see the fibres of the pellets in her shell which was thin but no where near what she has been doing.  Fingers cross she will continue improving......  Only downside is that Daisy has ceased double yolker delivery.  Never mind if they carry on with 4 a day that's still 24 if they have a day off each, no where's that egg custard recipe... :roll:
