Over the years I've ordered a total of about 75 chicks from three different hatcheries. Every one of them arrived alive and lived. It is very possible you can lose one or some. It happens but I would not count on it.I intend to order 12-15. I figure a small loss so I figure I end up with 10-12 at most.
However I do count on getting more roosters than I want, I think the min order is 5 some places, 3 the other. Some places only offer straight run which means mostly roosters. I intend to give some away or sell some to friends... Then you must think ahead to when you hens get too old too lay, and your too attached to the birds to kill them, and your too accustomed to those yummy fresh brown eggs.. would be nice to have a brooder to keep fresh birds on hand.. Im not totally opposed to a brooder outside the coop, but I have zero space anywhere else unless its my living room floor. no ty on that.. lol
