Ok, so I bought some silver penciled rock bantam eggs from someone on BYC, they should be here anytime now. This will be my first time hatching. My hubby and I are going on vacation on March 19 for 9 days. My question is...should I put them in the bator asap and just have my 19 year old son keep an eye on it while I'm gone or can I wait til the 29th when we get back to set them...?
