So my EE roo who is now about 13 weeks has been giving and enthusiastic crow for quite some time now. The last few days he is crowing but then a werid thing happens. Have you ever had pneumonia and after you exhale then your lungs still squeeze out one last weird bit of air? Well he gives a good crow then this odd nearly silent "echo" crow. A friend said he sounds asthmatic. (she is not a chicken person) he is NOT sneezing, coughing, runny nostrils. He IS eating, drinking but acting more aggressive with the girls than usual. So....any ideas? Is something wrong with him? The weather is great and other birds are acting normally.
