good book on raising foals

Hi everybody
I wonder if anybody can recommend me a good book on raising\training foals? My last "baby" is about 4 years old so I've forgotten half of what I knew about raising baby horses. Now quite unplanned one of my mares went visiting the neighbours one weekend and came back pregnant. We didn't actually realise until recently and now it seems she's about 9 months along so the countdown begins! The foal will probably evevtually be a cow pony like his mama.
