Hello!
One of my hens, Comet (a Sapphire Gem hybrid chicken), is 3 1/2 years old and I have noticed some things that are not normal for her.
First, to give some context, I was on a 3 week trip this past summer and my chickens went to stay with some of my friends at their home during that trip...
I have two hens getting into their golden years (they turn eight next month!) and four hens who are still active layers.
One of my older ladies I am fairly certain only lays once every few months. My other is a Sumatra, and she will still lay every day for a week, go broody, then stop laying...
