You need to get a baby monitor if you get more and you should be able to hear any ruckus going on inside there when you're sleeping or in the house. They work good.That's what i thought, they were all very big (may have been close to 9 weeks I picked them up from my local feed store and they had a mix of 1-2 weeks olds that i picked from) and my full grown chicken and ducks i thought would be a deterrent to something small like a rat. I put the food up at night and it's stored in an airtight container and the run backs up to my house on one side and has chicken wire other than a screen door on the other 3 sides. I don't have any hawk cloth over the top because it does back up to the house and that usually deters the hawks that a out in droves this year.
