Age Estimation:

  • Age estimation can be based on tail, foot, arm, or leg length or combinations of these measurements.

  • Body weight should NOT be used to estimate age.

  • Use these tables only as a guide. They do not take into account regional differences in size or variations in size due to sex.

  • It is important to weigh joeys regularly to confirm growth.

  • Overfeeding can cause diarrhea, so feed the suggested milk volumes in our tables.
