The best time to start breeding your finches happens when they're about 8 months old. There are finches that are highly dimorphic, meaning one can easily distinguish their gender by simply checking out their colors. An example of this is the Zebra finches. Society finches, conversely, can be a bit challenging on this department because they don?t have color patterns that tell whether these are female or male. One technique in determining the gender of the finches is as simple as placing at least four of which inside a cage and watching which birds get attracted to whom. Once spotted, you can place them in a separate cage in order to start breeding finches. Just because society are capable of doing something should it mean we have to? When you view this question in terms of Assisted Reproductive Technology (ART) this question becomes extremely personal due to its religious connotations. It is estimated that 7.3 million women are affected by infertility leaving many to believe that medical research and treatments should help these women fulfill their wants developing a child, yet some religions state otherwise.
