hey alaskan-- if you had a white heat lamp and turned it off even for a week, that might trigger a molt. If it was a red lamp, it shouldn't matter. Good luck!
I just had a late-breaking idea. Are your hens free-ranging? Because in the last couple weeks, I've been having troubles with my hens "not laying". Yeah, so they've been laying, just in the shed, under the porch, in the doghouse, etc. They are now in an enclosed run most of the day.
Try moving the trap, and changing the bait. Also try putting the trap in a "tunnel". They like to run though holes against walls, so make sure the trap is in a kind of concealed, hidey-hole kind of place.
GROSS!!!! I read in Gail Damerow's book that they have to have worms REALLY BAD to get them in the eggs. My girls have some tapeworms. I've never seen the other ones.
yeah, ridgerunner is right about the worms. They would have to have one heck of a worm problem to totally stop laying. I know my hens have some worms, but they're free range and just gonna get them, and I don't have any problems with no eggs.
Rats will steal the eggs, but they would probably be messy about it wouldn't they? I mean, wouldn't you see eggshells around?
Have you by any chance had them under a light/lamp over the winter and suddenly turned it off? This happened to my friend who had a white lamp on her hens for a long...
