My chickens make these weird noises. they almost sound like they are whining. I hate discribing sounds, but it is like braaaaaaawwwwwwwwwwwwwwkkkkkkkkk braaaaaaaaaaaaaaaaaaawwwwwwwwwwwwwkkkkkkkkk, brawk brawk BRAAAAAAAAAAAAAAAAWWWWWWWWWWWKKKKKKKKKK! Are they as miserable as they sound, or what? They always do it. So they want something or are they just making noise? Please help.
