Hi, I have 3 chickens, all of whom will be 1 yr old in March. We're in Canada and to say it's been cold, even for us, would be an understatement! We've had so much snow and freezing temperatures, it's been a little frustrating! But through it all, my hens have been laying faithfully daily (as a matter of fact, they went on a 6-week 3-eggs-a-day crazy lay schedule before one even took a day off!) Because they've been such frequent layers, I've become a bit concerned over the past few days. I've only been getting 2 of the 3 eggs for 4 days now. Keep in mind we're right in the middle of another cold snap--2 weeks of -30C at night. I'm hoping that it's totally not a big deal; they are all eating a TON, moving around, making chicken sounds, and their poop looks pretty normal, from what I can tell. I've read some stuff on worms, parasite, lice, mites, and don't think it's any of those things. I guess one could be eggbound, or beginning moult, but again, it's hard to tell without picking them up and inspecting them. So, my question is, at what point do I start to worry and go out and give each of them a physical? Also, if I can narrow it down to who isn't laying, does it automatically mean something is physically wrong with the hen if she's stopped all of a sudden? Could one hen just be particularly fed up with the cold temps and has gone on strike?? Thanks for any help!
