Afternoon all, I'll be picking up my first batch of chicks next week Wednesday and have a question about my brooder. I've got 31 chicks coming and plan on keeping them in an unheated garage (in northern Wisconsin) for about 5-6 weeks so I've built a pretty big brooder for em' (4x8x36"). To keep them away from the concrete I put a 2" layer of foam in the bottom with a piece of OSB over it...I'm going to install a divider with a removable door so they are restricted to one half for the first couple of weeks. I plan on allowing them to use both sides (with 2 heat lamps) and be able to "herd" them to from one side to the other for cleaning (once they outgrow one half of the brooder). I'm also planning on installing a hinged cardboard top with holes that I can slowly open up as their heat requirements decrease...and the weather warms up.... I'd really like to keep the cardboard and OSB in decent condition so I can use this brooder again if (or when ) I decide to get more chicks next year. (12 screws and the frame comes apart and that's 1/2" cardboard from diesel engine shipping boxes!). I'm aware of the puppy pads for the first week, then I plan on either pine shavings or pellets (depending on what is more "economical" at our local and helpful feed mill) but I would like to put something down to prevent moisture from water playtime and droppings from impregnating the cardboard and OSB. Can I safely use a heavy plastic liner (like 6 mil painters plastic) to line it? Or will they eat it? I have a very attentive better half that is already planing on perches and toys to keep the chicks occupied but I'm still concerned with them picking at the plastic...I've also thought of the plastic panels people use in milk houses with about 12" running up the sides and sealing the corners with food grade silicone...but that's kind of costly and considering the coop my better half wants me to build, I have to save as much as I can when I can... Thoughts would be much appreciated!
