Using a Space Heater as a Temporary Heat Source & Bald Bumps Near Chicks' Shoulder/Neck

[Folly's place]

My coop has heated bases for the waterers, and no other supplemental heat. Chickens that are feathered out and appropriate for the climate will be fine in a well ventilated and secure coop. In really cold places, like Montana, or very north, things may be different, but otherwise, let's define 'cold'. Here occasionally -20F, but not for long, all was well.

I stand corrected. I copied the below from the poultry site.com
I apoligise @feathermaid, i have only observed the down feathering being lost in all my years of raising chickens. Creating all that dust in my brooders. I will be looking more carefully in the future for baby feathers. Thank you for teaching me something today!

"The chick goes through one complete and three partial moults during its growth to point of lay, after which the mature bird normally undergoes one complete moult a year, usually in autumn although this depends on the time of the year at which the bird commenced laying"
