My goose has laid its first four eggs. I found three eggs on the 17th and guessed that it must have laid on on the 13th, one on the 15th and one on the 17th. It fitted the theory nicely when I found a fourth egg on the 19th, but then it stopped. No egg yesterday the 21st, and no egg today. Should I be concerned? I worry about an egg being stuck. The goose seems fine, active as usual, though it hasn't spent much time nestbuilding the last few days. The weather was mild when the laying started, but now we're back to below freezing again. Can that be the reason? Can they skip a few days and then go on laying? Or can the egg season just be very, very short? Or should I rush to the vet?
