This happened when my yobo and I were dating. I was very confused; being a native English speaking, it never occurred to me how close these two words sounded. It is quite a common mistake for learners of English to make. Once I was teaching ‘the rooms of a house’ to a group of middle school students and I showed a picture of a kitchen. An excited student blurted out “a HEN!”
For my yobo:
This is a chicken:
This is a kitchen.
And this is a chicken in a kitchen.
