Hopefully the fosterers will fall in love with them but for anyone else in the same situation who go down the 'living outdoors' route, please remember that if you are not fenced in, the children may run off and if they are not chipped, can be regarded as 'abandoned' if they are picked up more than 500 metres from home (now there's an idea !). So for the non-fenced garden you may have to consider a chain, which has to be 2.5 metres minimum with access to shelter, food and water. Or, of course there is always the wire and electric collar system - pricey but worth it if you really don't want to lose the children.
