I am trying to run protein BLAST alignment locally through BLAST+ and want to download the nr database. However, due to the large size of the database, I'd like to only download the portion of the dataset that corresponds to organisms I am working with: Mouse and chicken.

I looked at the NCBI guide and it gives a command to download databases: --decompress nr [*]

However, I am not sure how to specify an organism specific download. Please let me know if you have a recommendation. Have a good evening.

You are best off downloading mouse and chicken genome fasta files from NCBI datasets and then creating the database yourself. You can't download organism specific subsets of nr database.
