No they are all at least 2 years old... a few older. They have been molting for the past couple months but are all filled out again. I am only getting half the eggs I should with 17 - but this I thought was because of the molting. This has only been going on for a couple of weeks. It's cool lately. There are a few that have yucky butts and I have started some ACV for a few days and then will give yogurt after. I'm stumped... beginning to wonder if I have a bad batch of feed. I'm so sick of all the crap they put in feed unless you are willing to pay $38 a bag for scratch and peck feed. I need a recipe I can mix myself, like we do for our cows.... no GMO's and as organic as possible...

Edit: I just realized that (some) the chickens have almost like diarrhea - very watery with bits of chunks in it. That's why the rears are dirty. But I am talking a watery mess on the floor or outside in places... what the heck is going on?? I got 5 eggs from 17 chickens tonite... they don't act sick??
