My mum has seen one tonight in the run. We assumed they were around as it's an allotment site full of hens (& other stuff) next to a stream but we had only seen mice until now.
The run has a couple of feet of mesh spread out from it all the way round which is covered in weed fabric. But of course rats can dig far!
Food is kept in the shed overnight and sacks are in a plastic box. It's hung during the day.
We haven't been shutting them in at night, should we start again?
What else can we do?
