So I heard kale is good for my cockatiels, so I've been giving it to them daily. Now I've had no issues with it (unless mystery yellow pee that the vet doesn't understand could be related?? Anyone know?) but I've just read that kale has high levels of lutein in it. I also read that cockatiels are not particularly good at dealing with lots of lutein, sooo...? I was giving the kale to them because I heard it was good (I assume it's said to be good because of the high b-carotene levels which is good for them and they ARE able to deal with) but this lutein stuff has thrown me.
