I have 1 black sex link hen who is 42 weeks old. Also I have 2 EE hens who are both 39-40 weeks and a leghorn hen who is around 39-42 weeks. My sex link has been "squating" for 4-5 weeks and my EE have been for around 3 weeks. My leghorn hen was given to me and she had layed an egg once, before I recivied her. I've had her 4 weeks. Non of my ladies have layed any eggs. I have boxes with fresh woods chips they 1 1/2 feet off the ground. They get purinas laying crumble with crushed oyster shells. Also a Handful of grit every other day. They also get fresh lettuce, tomatoe(not the leaves), fruit and veggies even some yogurt (as a rare treat)... They are kept in a XXL dog kennel with wooden roosts and shade. They have two different water things. Am I doing something wrong?
