I wonder about the shorter days and also the temps. Hi - I would light them. 14 hrs. is what they would need. They might be a little young yet - heavy breeds often come on much later than lighter or production breeds. Don't force them too early - causes problems.
Golf balls is a good idea, too.
Don't worry, they'll lay when they're ready. Hey - congratulations. Light would be good, now. This is a private posting area. A valid username and password combination is required to post messages to this discussion.
