We have a Silkie who has been on one egg for 18 days today. We prepared her a box with food, water, and shavings on the office upstairs to prepare for hatching and get her out of the coop in case the other birds didn't do well with the chick. We moved her last night when everyone went to bed. She put her egg back under her once she got over being ticked at the move....a couple minutes. This morning my husband checked on her. She had moved closer to where the food was but the egg was beside her. He put it back under her. I checked her a little later and she was still sitting on it. I'm concerned she's rejected the egg. But everything I read said to separate the hen and egg from everyone else at some point.
