One of my 3 hens just died a few weeks ago. About a week ago one of my remaining hens started to squawk her head off all day long. She's molting and not producing any eggs now, so it's not the egg song. Could she be lonely/bored with only one friend left? Any suggestions? I hung a head of cabbage for them to play with and so far they are just ignoring it. I live in NYC, so I'm desperate to stop her shrieking. She actually sounded like a rooster today! Thanks!
