You better order more than two for any unexpected losses.
To all that read this forum: This is by far the best advice anyone could pass on to you.
All of the "experts" i.e. universities, breeders, etc. suggest to order and or purchase 5 - 10 percent extra. This is probably the most common mistake made by not allowing for losses. After all, this is not a perfect world we live in, and losses are inevitable. Losses occurr in all animal species as well as human beings. It is by far less stressful to deal with an extra chick or two as opposed to losing.
Please do yourselves a favor and order an extra or two and please prepare yourself mentally for the possibility of a loss.
