Hi everyone!!! New on here and I really need your advice...PLEASE. I have hens that were born in March, and are free range. I also have 1 rooster. I have had chickens for 4 years now and have never had this problem. ...they are not laying. They are happy and healthy. No stress, let out of the secured coop in the morning, free range all day and return to the coop at dusk. They mostly hang out around the house, garden, or around the yard. They were given chick starter when young, graduated to the coop, free range without supplements. I had free range hens for the last 3 years with no laying issues...so now I started with Dumors layer crumble. What's going on???
