Hi, our silkie hen is very broody over one egg that we have a candled and we see it slowly changing and even some movement in there (is that possible?) The only problem is that this egg is 36 days old. She's new at laying and at first she had no interest in sitting on her eggs but she seems magnetized to this one particular egg. We destroyed the rest of the clutch because they were over a month old and we couldn't see anything inside of them but we held onto this egg because there was an obvious bloodline when we candled it. Now we check it every couple of days and there's definitely something inside, just wondering if it's a lost cause because the incubation period is typically 21 days. We've only had our chickens for about three months so we're new at this and need some advice Thank you in advance!
