Do the wires offer some sort of heating for them?
Yes they do offer some warmth. Also good place to perch and there is not much snow build up on them. Good vantage point for the pigeons also to see predators.
For a chook , a nest isn't comparable to a three-mattress room ranch -- it is a place to maintain eggs and toddlers secure till they are grown. So nests are basically used while birds are having toddlers. while a grownup chook has toddlers to guard, it is going to return to its nest and sleep in it. yet something of the time they are able to sleep everywhere they like. Many birds sleep perched on branches, far removed from maximum predators. Others sleep status on the shore, or whilst floating interior the water, or maybe whilst flying! How do they take care of that? maximum birds can permit a million/2 their brains sleep whilst the different a million/2 is unsleeping!
As it gets colder, heating units require more and more energy as people use them more. As the current is increased, the wires heat up even more than they normally do. Standing on them offers the birds a free source of heat.
