Hi! Me again What size heating pad and brooder space do I need for 15 day-old chicks? I'm going to set up an XL plastic dog crate with the MHP in our run, just want to make sure it will be big enough for them. I can possibly set up 2 MHP's if I need to but our budget is limited so I'd rather not if not necessary I will make them additional weather shelter as necessary come winter. I'm starting them outdoors, in VA, where by the time they arrive (around May 1st) it will be averaging 50's (nights) into the 80s (days). They will also have another shelter right next to the crate - a big nesting wooden box. I'm also looking for some pieces of fencing or cardboard to block of the rest of the run so that they don't get too far from their heat, food and water for the first couple of weeks. P.S. if there are already good threads about this topic that you can point me to - as I'm sure there are - please let me know! TIA for all the input and help. Noi.
