In a few weeks I am getting TWO shipments of chicks (Hi, I'm Tam'ra, and I am a chicken addict.) but due to circumstances beyond my control, They will be about 6 days apart in age. There will be 48 in all (I must be mad!) and I was planning to brood the lot of them together in my greenhouse. It's a 10 x 20' room where they will have free run of 90% of the floor and a large brooder box with a heat lamp in one corner. There is currently grass growing on the floor and I have a 7 gallon waterer and a 20lb feeder to put in there. The dogs patrol the yard outside, and by the time the chicks arrive I will have the window vents installed so predators, overheating, and humidity will not be a problem. The only potential problem is the chicks themselves. Will the 23 older ones pick on the 25 younger ones? The older ones will be straight run buff orps, speckled sussex, and red broilers. They will have lots of space and things to eat... Will it help? Or am I setting myself up for disaster?
