  Recent developments in calculations of low energy nucleon properties
utilizing effective chiral field theories with explicit spin 3/2 matter fields
are presented. In particular, the role of Delta resonances in microscopic
calculations of the anomalous magnetic moments of the Nucleon is discussed and
a comparison to lattice data is performed. Furthermore, the impact of Deltas on
the isovector Pauli form factor of the Nucleon and the problems one faces in
calculations of the isovector Nucleon-Delta transition form factors are
addressed.
