How to phrase entree option in RSVP?

I am finalizing the details on our RSVP website before sending invitations next week. We are having plated dinner and our venue said we will select the entree for everyone. We are choosing a chicken. The wedding package we were provided says the menu is subject to change, so I don't want to tell guests the exact entree in the RSVP only to have it changed later (i.e. different type of chicken entree).

Currently I have "do you have any dietary restrictions? the main entree will be chicken." Is that sufficient? Unsure of the proper etiquette. I may be overthinking this.
