Hello and welcome to the family, Allie, glad you could join us and we look forward to hearing more about you and these two greys. I just love your login name, biteable, I guess that says it all.
I am sorry you have such a tough time with Puddy, but like LMG said they choose who their favorites are and there is not much you can do about it. You could be the one to give her treats and such and that might win you a little attention from her.
I have somewhat of the same problem with a sun conure and one of my granddaughters, the conure hates her and looks for her when she is here and if she gets any where near her she lunges to bite her. I have to keep her away and usually in her cage when she is here.
Please read thru the many threads on various topics for lots of useful information and do not hesitate to ask specific questions you may have. We will do our best to get you an answer and help you in any way we can.
If you have some pictures of the two greys you would like to share with us we would love to see them.
