1 yr+ Timneh started doing the baby bird hunger cry...
We have 2 Timneh African grey parrots, Teancum, a 7 yr old male and Abigail, a female just over a year old. About 2 weeks ago the Abigail started becoming aggressive towards the Teancum. She started pecking at him for no reason. Now Teancum won't come out of the cage hardly. She also started this baby bird hungry crying thing.
I was wondering if these changes in behavior are because we changed their diet. They were on a brand that was mostly seed and now they are on pellet and cooked/ fresh food diet. Abigail started the baby cry when we started feeding her the cooked food by hand also. Could see have regressed to wanting to be hand fed again? Why the aggression towards the other bird? Any help would be appriciated.
