Hi to all
Thank you all for your advice

Gilly your idea sounds a little bit wicked but might just work but I will leave for another day

John and Alan your comments are bang on, one of the hens is laying soft shelled eggs and as Carlseawolf has said soft shelled eggs are due to a lack of calcium,
So how do I correct it, they are fed on layers pellets and they also have tray of oystershell grit, also they get some treats like rice/pasta every now and then.
John as for the magpies the hens are in an enclosed run but I will try hanging the strips of black plastic you recommend
Once again thank you all for your help
Kind Regards & Best wishes
Kevin
