I have had my male peacock for over three years and he is apx 10 years old. Has always been healthy. Apx three months ago I was given two females. They were confined for over two months before being released to roam. One laid six eggs, began to set for apx 12 days, then suddenly died! The other female looks fine other then having some mites which have been dusted with sevins. But my male sounds terrible!! H e has been getting more and more horse for the last week and now can not scream. He seems very healthy. Eats well and drinks good. behavior is fine otherwise. I looked down his through and felt his crop tonight and all looks normal but I can not figure this out. Someone please help us to help him!!! Thank you in advance!!
