I have a Silkie tat has been sitting on 10 eggs for a week. Today she was off of them and sitting in an empty nest. The eggs were cold, but I put her back on them and she started tucking them under her like all was well. Hopefull they will be okay. So far she is still on them. Why would she leave her eggs like that? I have a broody Cochin, should I give the Silkie eggs to her in case it happens again?
