Hi everyone, I am new to this forum & although I was raised on a farm with chickens, I have never had any as an adult. My mom always used her broody hens to raise their own chicks, so I might need a tad of advice here, since I'm expecting 25 new baby chicks by mail in about 9 days! Hubby has made me a 5' by 5' brooder for them. Before building it, I had looked up info in books & thought they said about 16 inches tall for the brooder walls, so thats the height that hubby made them. Now, after reading posts here & seeing pics, I'm starting to think they will be flying over that in no time! The chicks I'm getting are heavy brown egg laying breeds..Australorps, Barred Rock, White Rock, Buff Orpington, & Americana. What do you think? Am I going to have problems with 16 inch high walls?
