I have almost 2 years old African Grey. What you guys think I should introduce nest box as they are chewing almost all the woods and perches,feeding each others.
I know nothing about breeding CAG's but 2 years sounded too young for a large parrot, so googled what Internet says about age breeding - somewhere I read that they are able to breed at 5 y'o but usually at 7 y/o they breed successfully
Yup, way to young!
Please understand that there is a vast amount of knowledge that needs to in place on your part, prior to breeding Parrots. Having an Avian Vet available is also a great idea.
