Okay - so my broody has been sitting for 21 days and started hatching yesterday. More hatched today. (5/5 & 5/6 hatch) Mixed breeds and sizes. Thing is, those chicks belong to someone else, who wants them back. So.... Tomorrow, I'm going to buy some chicks who were born 5/3 and put them under Buffy tomorrow. Question: is it better to a) put the 5/3 chicks under Buffy while the 5/5 chicks are still there, so she thinks they just hatched (she still has some eggs under her) and loses track of how many she has, or b)give the 5/5 chicks back to their owner and then put the 5/3 chicks under Buffy? c) something else?
