The nursery barn is obsolete after the introduction of the baby playpen, so Zynga may not be interested in fixing the bug. If you can't get a response out of them, you may have to delete it. I had a similar problem with another obsolete building, and I wound up deleting the buildling after getting no response from them for about 6 months.
