i ordered chicks from mcmurrays last week and lost a few in shipping due to the fact the post office put them in air conditioning. the hatchery replaced the lost chicks and then some. the new chicks arrived today, all healthy! so do i need to keep two brooders? the chicks are 6 days apart. we live off grid and run on solar, so i'd like to avoid having two heat lamps on if possible, they take alot of energy. maybe keep them seperate for a few days? what do you guys think? thankl for your help!
