Of the 26 chicks I ordered from McMurray last week only one survived. The order was lost in the mail and arrived 2 days late. One chick survived and is doing well. They are sending me another 28 chicks which should arrive tomorrow, fingers crossed. Is it OK to keep the week old chick in with the new chicks? This is my first time with chickens since I was a small child on my grandparents farm. Thanks.
