Okay, I've not used that before (you learn something new every day 
)
How will you authenticate to each server to allow it to install your public SSH key? You will probably have to provide a password, after all you wouldn't want just anyone connecting and setting themselves up with a public key to login as root now, would you?
That may prove a bigger headache than responding to the prompts. Is there a privileged account that is already able to connect to each server? You should then be able to force out the new public key (making sure you get the permissions correct) through that.
Sadly, hindsight is a wonderful thing.

ssh-copy-id
SSH-COPY-ID(1) BSD General Commands Manual SSH-COPY-ID(1) NAME
ssh-copy-id -- copy public keys to a remote host SYNOPSIS
ssh-copy-id [-lv] [-i keyfile] [-o option] [-p port] [user@]hostname DESCRIPTION
The ssh-copy-id utility copies public keys to a remote host's ~/.ssh/authorized_keys file (creating the file and directory, if required). The following options are available: -i file Copy the public key contained in file. This option can be specified multiple times and can be combined with the -l option. If a private key is specified and a public key is found then the public key will be used. -l Copy the keys currently held by ssh-agent(1). This is the default if the -i option was not specified. -o ssh-option Pass this option directly to ssh(1). This option can be specified multiple times. -p port Connect to the specified port on the remote host instead of the default. -v Pass -v to ssh(1). The remaining arguments are a list of remote hosts to connect to, each one optionally qualified by a user name. EXIT STATUS
The ssh-copy-id utility exits 0 on success, and >0 if an error occurs. EXAMPLES
To send a specific key to multiple hosts: $ ssh-copy-id -i /path/to/keyfile.pub user@host1 user@host2 user@host3 HISTORY
The ssh-copy-id utility was written by Eitan Adler <eadler@FreeBSD.org> as a drop-in replacement for an existing utility included with OpenSSH. BSD
