Chicks coming in Monday. I have 25 total coming from Murray. Mcmurray. 5 each of RIR, BO, Dommers, White leghorn, and Delawares. I have all my basic supplies. 2 feeders, 2 waterers, 2 heat lamps, starter crumbles, pine shavings, thermometers, and poultry nuttridrench. I will be building a brooder this weekend. I just need to know how big. I live in Va. So they will have to stay in the brooded for at least 4 weeks. Anybody that actually has raised 25 big stock chickens chime in. Just need to know how big to build my brooder.
