So my boyfriend got up early and went outside and he said he heard the chickens running and making noise. He thought they were fighting but once he got to looking he said they were "chasing a tootsie roll mouse" ( small mouse ). One I am frustrated that I am having problems already from attracting rodents and two I am mad I missed it! Three I am mad THEY missed it! He said it got away. I only feed what I think they can eat but there is always some cracked corn left. They are not to fond of it and it takes them awhile to get it pecked up. I keep all my feed in the house so I know that isn't attracting them.
