Ive read all the questions about chicks temperature, etc. but am still a little fuzzy---dont want to lose them now! I have them in my basement room---they are 3 weeks old Saturday (4-12) and doing fine--35 of them--standard size. I have a nice coop for them which I can put a 250 watt heat bulb in---will get the temp up to about 85 under the bulb. I am in northern Indiana--night temps right now can get down to 30 but usually more in the 40s. Would like to get them into their new home as soon as possible as the basement room has turned into a royal mess. Would appreciate your advice.
