Gee, that all sounds so familiar!

Love the pictures (I really love the different hues of blue on Laker) - in that top pic of them together I notice that Laker is on his tip-toes, my boys do that when they approach each other too, mainly Winston. I remember the first days they were all out together - pure chaos indeed! It still is chaos, but much more controlled.
Laker's reactions sound similar to Winston's - Jerry is generally the pursuer and half of the time Winston will fly away from him and that starts the on-going game of tag.
You're in for a fun ride!!
Just saw the next pic you posted - Winston is still not up to Jerry's flying level of expertise - he tires out and holds his wings out like that every night. If he's too exhausted I let him have a rest in his cage or if Jerry goes back to his cage I take that opportunity to let them both cool down - temps are getting hot recently but not hot enough for the air conditioner yet, but Winston may be the deciding factor as to when that gets turned on.
