Well, since she's not spayed, she certainly should be ASAP. She's 2 years old already!
But in answer to your question about training her to not go after the chickens....
I'd get her spayed first and see what happens after that.
But we've trained our cats not to go on the counters. They certainly don't when they know we're looking. The definitely do at times when they think we're not.
If you love the chickens so much, why would you risk their lives with a cat that apparently now sees them as prey - and that is something completely natural for a cat? I'm so unclear as to why building a fenced in area of your yard for the chickens is a problem. My grandfather raised chickens - not for eggs, not for meat, but for love of the breeds. He had many champions in many breeds. He loved them, and they were family. But they lived in the barn or a fenced in area of the yard. They were not unhappy. With just two chickens, they really do not need a very large area. It is beyond my comprehension that you would give away a cat because it is doing something natural to it - when there is a perfectly reasonable solution.
