I only have two chickens left from my flock. One is a little polish silkie and the other is I presume a nankin, they are inseparable . I have noticed this problem only happens during the summer months. Early in the morning the Silkie starts screeching which goes to a fever pitch screech. You would honestly think I was trying to kill it. The screeching goes on for about 3 hours. Not to be out done the Nankin then decides to join in. The noise is dreadful. Chicken clucking is lovely to hear and I love it when they announce the arrival of an egg. Unfortunately the screeching is getting out of control and the neighbours will soon complain to the council. I don't want to part with them as I rescued them but what choice do I have ? Any suggestions as to how I can get them to squawk less ?
