I put pepper flakes in their food and after 2 days, I found this! First egg since Dec 9th! Now I have a few questions, I have two roos in with my girls. I know my bantam cochin Johnny Cash mounts my cochin Luna. But how can I tell if this egg is fertile? I highly doubt it's from Luna she's never laid an egg. Do I just keep it warm for a few days and see if anything forms? It was pretty cold when I picked it out of the nest.
