We own a 150-year-old farmhouse in upstate, NY--the kind with the barely 6' ceilings and giant monoliths of stone as the foundation. The house is a beast! The basement has your typical old-house make up of several rooms. It's typically around 55-60 degrees year round down there. BUT, the boiler room, which is probably 12'X12' is a toasty 75-80 degrees. My husband set up an awesome brooder in there and we had 100 chicks of 8 different breeds arrive from McMurray on Monday. Here's my question. Is it a bad idea to brood in a boiler room? We are down to 87 of the original 97 chicks that made the journey in a cold blizzard. 8 of the 10 that died are all the same breed--Blue Andalusian--and were teeny tiny & weak. Even the remaining ones of this breed were tiny. But then we also lost one seemingly healthy Delaware and another Easter Egger on days 1 & 2. Could my boiler room be emitting gases that are bad for the chicks? We have everything inspected and checked and have a new boiler as of a few years ago. After day 2, I got panicked and opened the door to the rest of the basement for more air flow. Temps are correct, heat lamps are on one side of the brooder allowing for a "cooler" side, I have three waterers and three feeders... What am I doing wrong?!? All I can think of is the canary in a coal mine!!!
