I have a.... what appears to be an austra white. She's of unknown age, perhaps best guess is 16-17 weeks. Lately, she's been very amorous around my dominant rooster. He's about 15 weeks old. She coos and clucks around him, following him everywhere. She preens his neck feathers and even puts a foot on his neck to get his attention. Is this normal? Does this mean she's ready to lay eggs?
