This may be a stupid question, but I thought I read somewhere that a 'breeding' pair could be siblings or parent/child, is that true? seems odd, but I thought I would double check. We have 2 adult emus and 2 young ones that came from one of the adults. We are curious what our chances are for egg production. The father of the two young ones was killed and we have raised these young from birth (they are 6 months old now). We know we still have one adult female, but are uncertain what the other one is, and are just curious what to expect with this upcoming 'mating season'. thanks !
