one of my roosters seems to have lost his voice. he was crowing this morning and it was pathetic, he was very hoarse lol. this afternoon when i went out again i saw him keep trying, and hes even more quiet than earlier! him and one of the other roosters crow the most out of all of them. allllll day long they are back and forth. is it possible he actually lost his voice, or is this something i should be concerned about?
