Thanks, this is good to know!I would say that I haven’t seen any of mine become unhealthy. One time Tassels lost about 15% of her body weight.
With hindsight I may have been overly worried about that. She never lost condition if that is the right way to describe it. What I mean is she never looked ill, her feathers were in good condition, and she wasn’t lethargic when not sitting.
And in reading I have done subsequently I have learned that 15% body weight loss may be normal.
I think I just lost my nerve!
Maybe I need to go broody...
