Yes, mine has not yet frozen either. It has gone down to -11 C (12F) and was perfectly fine. All waters frozen... :/ Time to get to work on my tin can heaters for the waters. I can't afford heated waterers for all the different coops. I usually have a chick pen, a rooster pen, a bantam pen and the older chickens pen (they are all coops I guess). Last year I didn't have any birds who wanted to free range in the snow. Maybe they will be more daring this year. I have 100+ more birds, so I'm sure someone will give it a goIt was 22 this morning at 7AM when I went out to feed my flock. Water was frozen. The tarp over my FF trash can (plastic) was frozen, even the lid was frozen to the can. BUT - the FF was not frozen in the slighest! It was warm and bubbled when I stired it. For the time being I'm leaving my FF outside on the stoop to one of the chicken houses.
My one question is about their poo. Most everyone mentions how much firmer their chicken droppings are. Mine are still messy. Any suggestions as to why?

As for poops - I have some runny poops throughout the day. As long as that bird isn't pooping that way every single poop, I think it's normal. I watch them poop - I'm weird... and the younger ones seem to have runnier poop than the older ones, but do have perfectly solid poops later in the afternoon.
I spent so much time watching chicken TV yesterday. My inlaws and evil twin nephews were home, and I needed to escape. When they kept coming down to the barn the day before, I nearly had a panic attack. These twins asked me to slit a chicken's throat so they could watch it bleed.
Future serial killers? It makes me boil. They are just 8 year olds, but my other nephew would never say that.
I put a lot of ACV in my FF and water, and still get occasional runny poops in the AM.Maybe it's time to add a little of the ACV to the mix and see if it changes their bowel performance? I've not had any on the FF to have runny poops except the normal cecal poops that all chickens have now and again but they aren't exactly runny...just moist, as per usual.

They should be eating more in the fall due to less foraging available. Must be something going on in the taste of the feed. My flock has days where they eat less than others. The rainy days - more is consumed.I'm glad you said this because I was thinking the same, I'll dump and start over that may be why they aren't eating it as good and I thought it was the weather.
