Ok so I have my 3 week old bronze turkeys in the house in a cage brooder that was big enough for 8 chickens but is looking pretty small with even 3 of the 3 week turkeys in there lol. I am wanting to build something outside for them to "brood" until they can be let out into the fenced in area that I have for them behind the chicken coop. I have a half shed leanto like shed with a 20x40' fenced area with welded wire fence top that I was going to let them live in when they get older but I know they are not ready to be turned loose around that yet, I do not have a garage but I am pretty mechanical and have a good supply of lumber, welded wire, hinges, locks etc etc etc that I can use to build something. What would I build? Do they need a three sided wood enclosure with one mesh and screen side or do they need a 4 sided wood box? I live in NW Missouri and our average daily temps are supposed to be in the mid to high 80's to mid 90's and overnight lows in the high 70's to low 80's for the next couple weeks. I have a good brooder light, feeders, waterers etc but I am reading that they need to be in a brooder for 3 months and I know the cage brooder I have them in will be way too small at 3 months because its already too small.
