A few years ago when we started this 'journey', we decided they needed to be kept warm in the coop. 40 chickens, needed around 3 heat lamps PLUS heated watering.
where we got that idea i dont know, all i do know is that it got EXPENSIVE. all the girls by winter were fully feathered and probably a month away from laying.
the next few winters, we decided it to be wise to just add one to the coop, still very costly. but that winter there was only four, so they didnt have too much body heat to spread around (all the others got taken by animals, foxes? maybe, but it took 36 birds in one night.)
This winter, with the 60 birds, there will be no heat lamp.
