and I'm afraid of using a heating lamp out there. We would have to run an extension cord and I'm a bit freaked out about a fire hazard to be honest. We bought them Friday, March 16 from Tractor Supply. I am guessing the little ones were almost a week old (I think TCS gets 1 day old chicks Monday morning) and the bigger ones were almost 2 weeks old. She sold us the bigger ones at a discount because they'd been there longer. We have 2 jersey giants, 1 silver laced wyandotte, 2 australorps, 2 orpingtons (we think), 1 black star, and 2 rhode island reds. All cold hearty breeds. We have had them in the basement in a brooder box with an infrared heating lamp. They started jumping out of the box within a week or two. The only two I don't know if I have seen jump out are the australorps. We have chicken wire on top so they don't get out unless we want to hold them. We have one sick right now, with what we believe is Vitamin E deficiency. We separated him/her just in case it's infectious. We are treating them all with vitamin/electrolyte/probiotic water. So, back to my question! It is just so cold here still. This week highs are in the low 30's and even high 20's this weekend. Lows are in the low 20s. Next week it will gradually get to highs at 50 or above. I think it is time to move them to a bigger space. They are more than ready to stretch their wings! Will the heating lamp be necessary? If we secure it properly, is there still a fire hazard? How is best to deal with it at this point. This is our first go at having chickens. Thank you so much for any advice!
