This issue of 1-3 eggs a day has been going on for close to 2 months now..lately 0-1 eggs. My hens will be 2 years old in April. I noticed a changed after the rooster was killed by my dog, he died protecting his hens in the coop. (my husband didn't latch the door properly and dog got in) Does loosing their rooster affect them to this degree? If so should I get a new rooster? They have all laid so well even through last winter, I was getting so many eggs usually 9-11 a day. I have 2 Americanas they have not laided in over a month. 2 Barred Rocks, 3 Isa Browns, 2 RIR, 2 black sex link. Nothing has changed with food, grit, oyster and veggie scraps. I have a light in the coop (did the same thing last winter) that i started a week ago and that didn't change anything. Any thoughts?
