How wonderful! Pullet eggs! We are still getting pullet eggs too.. they're so cute though~! Someone left a message on one of my threads about using food coloring to tell. I'll go find the post and post it here for you.
Here's what they wrote: I never tried it, but maybe it works!? - Aimee
You can drip food coloring onto your hen's vents - a different color for each bird. The next eggs laid will have a slight 'tint' to them - helps you tell who is laying what.
