Hi there,
I am fairly new to raising chickens- we got our first flock this past spring as day old chicks. We live in Maine and it's been cold- but all had been fine so far. This afternoon I brought the girls out a treat of some raisins and bread. Yesterday, I had fed them a head of Romaine lettuce prior to seeing the news about possible E. coli contamination. I added a little warm water to their dish. I picked my daughter up from school then went back out around 5:30 to change out their water dish for the night and found one chicken pretty unresponsive to touch. The others were sleeping normally (they didn't have their heads flopped on the floor and their necks stretched). I came inside and after my son got home I warmed up a towel to go back out and see if she was just cold. It's been colder than tonight and they've all been fine. When I went back in (it had been about an hour and 15 minutes) there were now 7 chickens who appeared to be dead- leaving only 5 living. When I went out at 2:15 pm they all seemed fine and I closed them into the coop for the evening. There is no way for animals to get in- I am totally freaked out as to what could've caused this. I was talking to my husband and the only recent changes were that I cleaned their coop Wednesday and added a very light layer of coop and compost under the shavings, and I added a bag of feather fixer to their food because some were losing feathers. The one thing I didn't think of then, but I did now, was that I had given them a head of Romaine lettuce yesterday. I looked last night online and couldn't find any information as to whether or not chickens could be infected by it- but it was fresh. I buy the bag with 3 heads in it and they get one every other day usually. I haven't found anything online and now I'm wondering if we should even eat the eggs they've lain in the past couple of days. It's upsetting because they're like pets, I just don't have any idea what went wrong. Thank you for any help.
 
The biggest reason I don't think it was anything is because I don't see any marks and the chickens that are still clearly breathing along with the rooster were acting normal. I would think they'd be nervous and flying about if there was an animal in there.

You'd be surprised. Check for really tiny bite marks like pinpricks. Weasels are hard to spot and often take a flock by surprise.

You're right. My aunt and uncle caught one in time just before their whole flock died. it killed 14 of their 26 chickens. The thing got in through the floor. My uncle went out and got the thing in a bucket and you can connect the dots....
 
Wow I'm sorry too hear about this what a awful day. The only thing I can think of is to cold how is the humidity in your coop?
Same as it has been all winter I guess. We do run a 250 watt heat bulb in there. They all sleep on the floor in a huddle and not on the roost bar- I thought maybe the one was too cold- but jeepers- we had cold last week way worse than this.

I'll look for little foot prints around the outside as well- we just got about 16 inches of snow so it should be easy to spot.

It doesn't sound like they would die immediately once becoming infected with e coli at a level that would be harmful.
My chickens won't eat lettuce. But, I eat it almost daily. The recommenation was from consumer reports due to previous e coli outbreaks (nothing recent), but almost all produce can be contaminated (remember when strawberries were being recalled from certain locales?)
This warning regarding the romaine lettuce almost sounds like fear mongering.

Hmm if they moved to the floor from the roost they might be getting a draft up there and that could cause problems. Don't get me wrong they need ventilation but not draft. Is the roost higher than the vents or lower
