I have only ever raised small batches of chicks/turkeys never over 12 at a time. I am getting 30 red broilers from Ideal at the start of November and I need some help deciding how much room they will need at first. Its starting to get cold here w/ highs in the 50's and low's in the 30's so they are going to need to be in my barn in a brooder w/ a heat lamp. I hope to be able to free-range them a little but I guess that depends on the weather as they get a little older. I have started all my other guys in a 30 gallon fish tank, and then moved them into a 75 gallon stock tank. I use the 30 gallon fish tank because it seems to keep the heat better when they are young but I think this might be too small for 30 even during the first week. Any suggestions?
