I bet his or her birds were grumpy also. You cant raise a nice friendly bird if you are not nice yourself. Okay we have picked out a nice clean, friendly, healthy environment where the diet is good. Now we have to pick out a Quaker baby. I find it best to let the bird pick out me.
Birds are like people when it comes to who they like and who they dont like.
Ideally you should have 2 or more birds to pick from. I kind of play with them from afar. You will notice that some will come over and see what you are doing and some will run the other way. From the ones that come over and see what you are all about pick one and get him up to further evaluate him for compatibility. If he likes you it will be evident right off the bat.
