My chicks are 5 weeks old now, and I'd like to get them into the coop within a couple weeks. I'm going on a trip in about 3 weeks, will be gone for 2 weeks or more. I will have someone coming in twice a day to check on them (and the cat). So my question is, at 7 weeks old, what is the lowest nighttime temperature at which they'll be ok? My coop is 4' x 6', and I only have 2 chicks. I don't have electricity in the coop. I suppose I could run an extension cord, but that scares me, since we won't be home. Also, I wouldn't be able to use the red light, because that would draw the attention of my neighbors, and I'm not ready to do that..... How much heat does a regular lightbulb put out? What watt would be effective, if the temp goes down to, say, the 30's (quite possible, here in NH) The coop has several windows, perhaps I should cover some of them so it isn't too drafty? I hate that I will have to put them out, and shortly after go out of town, and not be able to observe how they're doing - although my pet sitter is very good about spending time with the pets, and will let me know of any concerns. To sum up: 1) At 6-7 weeks, what is minimum temperature (Ameraucana and Partridge Chanticler)? 2) What watt regular lightbulb is needed for heat?
