You should still write. You are a good a writer, but just because someone else wrote a story where the chick is taken home in a box too doesn't mean you have to stop this story. It should be of no concern to you what she writes
No need to go through other peoples stories with a fine tooth comb. Heck, you and chickenlovers stories are similar. But now that copyrights are getting involved with both stories, I'm getting leery about this whole story thing. And again, you are a gifted writer, no need to be manipulative of not writing on this one.
