And they they have stopped laying. Here is the summary: 1. Flock age - 8 of them were a year old in May. The remaining 10 were hatched March 1. 2. The "old" flock layed great all through last fall, winter, even in the almost 0 degree weather and the 100+ heat. (through the winter time without any heat or supplemental light). 3. The egglaying dropped off to about 1/2 when the 100+ weather hit and was here for a prolonged time. 4. The egglaying has since that time, continued to decrease (basically mid August i experienced the first decrease and it's been downhill since, with about 1 egg per week for a couple of months and now i haven't had an egg since mid October). 5. I see no signs of molting......they all look nice and fluffy and "normal." 6. They are eating just fine, no change in food (feeding flock raiser) 7. No visible signs of worms (lethargy, losing weight, visible worms in poo).. 8. i have never wormed my chickens. Any ideas? what can i do to jump start them??
