What is the age you cant breed a rabbit at?

they usually have to be 3 months old as one of mine are 3 and a half months old and she is pregnant and the male is 4 months so the male has to be 3 months or over.

You should NEVER breed a rabbit until it is 6 months old or has reached mature weight. To breed before is to risk stunting your rabbits growth and your do dieing during kindleing.
