Aloha,
I have that problem but the little suckers like to go in to the cages too. I found that out when I was feeding the birds and all of a sudden I heard a squeak. I look back in and see a chicken running around all fluffed up! Not only that but she has a mouse in her mouth. Well lets just say the mouse was extra protein for that hen. It was terrifying and intriguing at the same time. But if the gals catch them then survival of the fittest and by the way they have caught a lot since.
