hi fellow chicken lovers!!! i have 4 buff sussex chickens, 1 cockeral called Colin and he has 3 good lookin ladies called claire, nancy and gert. all around 4 months old!! i have recently noticed that one of the hens (claire) has become very very noisy!! it is more of a squark than a cluck!!! any ideas to what is causing this or why she is doing it!!! thanks!!
