I've found mice with chunks missing out of them in the coop before, the hens kill it but becqause they're bantams can't swallow it whole so they just pick at it.
I remember sitting next to the coop one day and seeing one climb through the bars, grab a seed and start munching. So I went (scaring the mouse away) and caught my RIR who was free ranging at the time and sat back where I was at the doorway with her on my lap. After a little while the mouse came back and my RIR got SO EXCITED in my arms!!!Her pupils were going crazy she started struggling to get away but stayed completely quiet! I let her go and she charge at the mouse and got it by the leg. This is when the other hens saw and ran over and by the end of it the mouse was a stump and everybody had had a piece... eww
The only worry with them eating mice is if the mouse has ingested poison as the hens can get secondary poisoning from eating it.
