We have two Barred Rocks that used to lay very well who have stopped laying altogether. They are two and a half years old, who molted last year once for about 2-3 weeks. I've heard they can molt for much longer... They used to lay in their nesting boxes just fine and especially well if they got out of their coop (free-range) regularly. I'd notice that if they didn't get let out of the coop for a few days, they'd lay fewer eggs. Then they were getting more "free range" time and over time they had started waiting to lay later in the day after I would let them out of the coop, and started preferring to lay in their favorite bush once they were running free in they yard. Then our Rhode Island Red got sick last summer and she died, she was our best layer, and sweetest little soul. The remaining hens (3) continued to lay pretty well and our worst layer started laying more often. Then my husband re-seeded the lawn for an upcoming home appraisal...I don't now exactly what was in the stuff, and I was trying to keep the hens in the coop so the new grass would take. But I felt bad for them stuck in there when they loved being out in the yard, so I let them out here and there to graze a little. At that point, less eggs came and then laying came to a complete halt. I searched the bushes for hidden eggs, hoping they were just laying in the yard somewhere. I didn't know if they were revolting to being kept in the coop longer or if something in the re-seeding process made them stop laying. When I wasn't seeing any eggs at all, I tried keeping them in the coop longer, for a couple of days at a time. Then a predator got into the hen house one night (probably a raccoon) and killed our Americana. Our two remaining Barred Rocks got away fine, but I also don't know if that traumatized them to not lay eggs even more. It has been over 2 months since I've seen an egg from my wonderful chickens that once laid so well...I am so sad. I have several theories of possibilities based on my story above, but since this is my first flock, I guess I am still new to this. I got them all as day old chicks two and a half years ago, and hand raised them. They've always seemed happy and friendly but I've definitely noticed them not as friendly after the predator attack...I don't know if they're molting, if something in that re-seeding sterilized them, if they were traumatized, or if there's something else in their diet I should be adding. Any advice? I'd so appreciate it, I'd love to have my remaining 2 girls happy and laying! I was also hoping to get some more chicks later this year, but want to make sure everything is ok before I do that. Many, many thanks!
