My African Grey is 8 weeks old now - from 5 weeeks old.
Feeding her 3 times a day, and I have placed fruit around the cage. She does not seem to be eating as much as 2 weeks ago (hand feeding). She has already climbed onto the 3rd rung of her ladder, exploring everything. She looks like a fully grown african Grey where 2 weeks ago she could not even climb out of her box.
The pet shop owner gave me a bag of food for hand rearing parrots, he did say it would last 2 months. It has only lasted me 2 weeks. My baby Nikita has grown sooo much.
