I haven't gotten an egg in several months and I have about 19 laying hens. Over the summer, they were laying although not like I think they should've been. I brought in 6 new pullets from a hatchery and from those alone, I didn't receive more than one egg a day...ever! And that was 7 months ago right in the middle of summer. Then in the fall, my hens stopped completely. I know the daylight/cold/winter slows them down but we're not talking "slow down" here; we're talking just complete stop. I have three new hens I raised that should've started laying a month or two ago, and...nothing. Last winter, my chickens came to a complete stop also. They're getting a laying mash from the feed store and supplemented with wheat and corn. I know there are different types of mites and things; can anyone tell me what would cause them to not lay at all?? I've had chickens for years and never had a complete strike before like these last 2 years. I think something must be infecting them.
