can you keep chickens in a barn with goats?

Just wondering if anyone has any info/thoughts on building a barn to house both chickens and goats. I'm hoping I can do this as opposed to building a barn and a separate chicken coop. I assume the chickens just need a space to nest and something to roost on? Should this structure be insulated in any way? I live in southern VT. Thanks

We used to let our chickens run free and they spent quite a bit of time in the goat pen, so not exactly what you asked, but hopefully it's useful.

For the most part the chickens and goats left each other alone. Occasionally one of the roosters would pick a fight with the Billy, but it never lasted long and nobody got hurt. The biggest issue was the chicken poop. They kept roosting on the side of the goat's water bucket (facing out of course 🤦) and in the rafters over where the goats liked to bed down for the night. It didn't seem to bother the goats, but it was mighty unpleasant to milk a goat just after it spent a night under an entire row of chickens.

There are ways to eliminate these problems, but since we also had the issue of our chickens eating everything in the garden we opted to pen them up separately.

Not ever having raised chicken or goats in Vermont, I wonder if the barn temperature will be warm enough for both chickens and goats in the coldest part of winter?

Just seems to me the chickens would need their portion of the barn to be warmer.  Having the barn partitioned off to create a sort of chicken house might be needed to keep the chickens warmer. And a way to heat that area maybe with a light?

I start many of my posts with "I'm not an expert but..." because its true :)

I have had Chickens in Maine, which I imagine is similar weather to Vermont. I kept the chickens in a mobile coop with hardware cloth on the bottom and two sides until December, and put them in an unheated, single layer plastic, greenhouse for the rest of the winter. A couple ended up with frostbite on their combs, most likely because I did not have enough ventilation for the humidity. Towards spring they were getting too hot. During the winter, there were no signs of them being too cold. Birds do not feel cold the same way humans do, and I think many chickens are far too pampered when it comes to temps. Get a chicken breed meant for the weather and you shouldn't have any problems. Mine were Black Australorps. For chickens it is more important to have good ventilation and be kept out of direct wind than it is to maintain a certain temperature.

Also, historically people would put all the animals together in one barn (mostly separated into stalls by species). This is quite normal, and I don't think there would be any problem (beyond what has been mentioned already, that the chickens may make a mess on or for the goats if not penned separately.

We raised goats with chickens. Until we got livestock guard dogs and didn't train them well with chickens.

Chickens are goats will get a long just fine. Birds have a layer of down that keeps them warm through winter. Goats have a layer of cashmere. Make sure the barn isn't drafty. That's not good. We keep a thick layer of straw on the dirt floor of the barn.

I echo the poop comments. If they are roosting they are pooping. haha Encourage roosting where it is easy to clean/compost, layer straw on top and not be a nuisance in goat feed, water or minerals.

I've had some chickens that would roost with the goats. they got along without any issue.
but don't let the goats eat chicken feed, its too high in calcium and will cause urinary issues in your goats.
the other issue would be things like Coon's. they have no fear of the goats and will kill off your chickens.
