I am in my first year of raising my chickens, it is now getting colder (20-40) at night and days (40-55), I live in NY. Winter will be here before I know it and I am trying to figure out how to make my babes cozy and safe. Their coop (about 8'x4') is inside our barn (the size of a 2 1/2 car garage), there are no drafts but has good air circulation. I have a plastic waterer which I have had a heating lamp (250W) pointed at at night so it will not freeze and to add warmth to the coop (not sure of the temp inside the coop). I have been speaking with other chicken parents and they say I am crazy for having a heating lamp on so soon and that they will be fine until the temp reaches below 0. I thought I would need to add a second heating lamp to add warmth due to the size of the barn itself (the walls to the coop are osb board on the bottom and chicken wire on the upper half), heat rises I also am not sure if I should keep the heat lamps on all day/night and if I should have a regular watt bulb on a few hours to increase their "daylight", they are still young enough that they are not laying eggs (hopefully in the next couple months). I also have a cement floor which I lay down pine shavings as bedding. Thank you in advanced for any advice you can offer!
