Could my Olive, green cheek yellow side, possibly be a hybrid? She has an odd splash of crimson red on her wings like I have mentioned before in another post. She also already weighs 72 grams as a 3 month old compared to Hazel at almost 64 grams. Hazel is petite for a greenie but you can see just how big Olive is compared to little Hazel, who is a year old. Olive also has a lot of black on her tail with a light red ring around each tail feather, about a 1/4" wide. When I first got her I was convinced the black was stress bars, and her tail was supposed to be the light red like other greenies. However my vet confirmed this as not being the case. And he answered my hybrid concern with a very vague, "Anything is possible." So what do you guys think? I purchased Olive from a chain petstore, and regardless of my attempts they will not release any info on her breeding although her leg band indicates Michigan.
