My 3, 3 year old Wheaten Ameraucana hens are out laying my 4, just turned a year gold sex-link hens. This has been happening slowly over the last couple months as each hen stopped laying. Everything has been quiet in their environment and no feed changes. Is this a sign that they will be poor layers in the future? I bought these girls as my main layers but they are majorly slacking and I won’t feed freeloaders! They look great, no molting signs. They just tuned a year old, do I need to replace them already? I’ve always had good luck with black sex-links, but this is my first experience with gold sex-links.
