Hi everyone and I appreciate your stopping by to help out with my foolish query. I hatched out a batch of Standard Cochin's (8 weeks old) and found that only one is worth keeping. I refuse to cull them, yet as they age, winter is not a time to put them out in a coop. We so have a addition with a cement floor, insulated walls with the exception of windows. we are looking at 6x6 area, would like to surround it in plastic , and here is the real dumb question, will a heat lamp keep them comfortable? Especially when it can get below 0 in another month or so. I miscalculated space and expected to no have as many hatch! Love to hear your recommendations!
