They are growing like crazy! And definitely eating loads. I’ve continued to give them fresh-cut grass/flowers and gravel; they always love that and gobble it up immediately. No worms yet, but I should try it soon.
I am fortunate to have them all still alive, although it has required several “cleanings”. There is a condition called 'pasting up' where poo gets stuck to the outside of their vent (bum) and then they can’t evacuate any waste at all; it just backs up inside them until their system can’t handle it any more. I’ve had to clean one of them a few times and a couple others once or twice. Hopefully they grow out of that soon.
They definitely do not like being handled and are very easily frightened. At the same time, they will adjust to having you around after only a few seconds if you are still and quiet. Interesting birds for sure :)
