FEATHERING
Dr Rob, I have many Gouldians and have bred successfully for a number of years. This year I have quite a few females with bald heads. They have no mites or other visable skin infection. They seem very healthy and some have bred young. They have a good balanced foreign finch, charcoal, iodine block, egg shell, cuttlefish, greenfood, gg food and a water mineral supplement. They also have meal worms every day as they live in a mixed aviary. mineral block grit also. I have heard it is due to a lack of iodine. They have access to a water spray 3 times a day and often use this, What could be wrong? Thank you
