Thanks guys!
Grrrrr we have a rat!!! Well probably more! my neighbours had them under their pigeon shed (maybe 15 metres from our coop) and spent probably 2 years getting rid of them with concrete etc. They have now moved in to ours. I'm devastated as I'm terrified of them. I saw a cheeky so and so at the feeder and at the waterer yesterday while in the garden. Starting to look at thigns to do. First is to get rid of food and water overnight I'm guessing. Anyone else had them?
I have just caught 19th rat in my car! I use simple mouse/rat trap and yellow cheese.
