So in my flock of 6 cockatiels I’ve noticed that 4 have extra orange blockages around the head and neck. I’ve got no problem with them but I was wondering if anyone else’s tiels have these markings or if they are maybe a sign of a deficiency or anything to worry about? I did wonder if it’s a side effect of having a mixed aviary, as that means there is a mixture of seeds available which include a canary seed which has little yellow pellets for colour enhancing. I managed to get pictures of the two who’s blotches are the darkest.
