Brolie,
You have two symptoms, smaller than normal poop, and straining. Birds hide being sick. To share my sad story again. My GCC whome I got knowing would have life long problems from an infection that closed one nostril for life from improper hand feeding. She had off and on infections in her sinus for life. Her last infection was years ago. A few months ago she had one drop of liquid in her working nostril. So ok here we go with infection again, made appointment to see vet next day. Her weight perfect, her alpiti perfect, her dropping perfect, her behavior active playful. Gave her some love and treats, went outside for 1 hour, came back inside, she was dead in the bottom of the cage!!!! My heart broken, my guilt still makes me cry. I watched her like a hawk, birds hide being sick!!!! Yes sometimes you get lucky and see something wrong, but there are endless stories of found dead, no previous symptoms. I felt like I should have seen something more, but my vet assures me they hide being sick......that's why two symptoms make me worry so much for you. I know you love her, and I sure hope it is nothing serious at all, but please know they can hide being sick.....
