i have a 1yr old aracuana x roo lately his "voice" has changed from a very loud crow to a softer crow which can barely be heard from the coop in morning, while b4 you would hear him loud and clear, he used to crow almost constantly, is it possible he stressed his voice box? it kinda sounds like he has larengetious. he's healthy otherwise no issues eating or foraging and finding food for the girls. is this a normal thing to happen w/ a roo or should i be concerned. thanks jim
