Miss Daisy has recently started making "crowing sounds" and she no longer hangs out with her sister chickens. She just kinda stays nearby them, but is getting kind of unfriendly. The other 2 chickens sometime seem to be afraid of her now. Last evening I heard screaching and I went out to check.....and she was on her sister attacking her. Today them seem fine. I only have 3 chicks and they are 18 weeks old. I have had them since they were one day old. I am afraid that Miss Daisy now needs to be called Mr Davey . I hope that I am wrong..because I will need to find her a new home (if she is a him).
