They can get along, I had a ginger boy whom grew up with the chickens and never bothered them, he even slept in their nest box which the girls hated and he still wouldn't attack them when they kicked him off. I have two other girl cats that weren't raised around chickens and lick their lips at the sight, I no longer let them out so its not a problem for me. so long as you raise chickens and cats together they will realize that they are family, I never really had to teach my cat that he just knew, but I cant say the same for other cats so do supervise when they are outside. only leave them alone when you are sure they are okay with them, you may think they are but be sure! all it takes is one hungry pet, I learnt that the hard way.
