I have a 8 month old silkie who seems to have gone broody today. She has been in the nest since early this morning. We only have 3 silkies hen and usually get 1-3 eggs from them a day. I am trying to decide if I should take the 12 I have inside and put them under her or put some of our RIR and BR/RIR mix eggs under her. If I hatched silkies I would sell or give away most of them. RIR or black sex links I would keep to add to the flock. Or I could always put a few of each which might be fun. How many eggs can a silkie sit on? Any opinions? My husband said we should wait until tomorrow and see if she is still in the nest box. If she stays in the nest box should I move her to a seperate pen? I have one that is 8x8 that I can use for that purpose? And if so at what point. Also if I leave her where she is and mark the eggs with a sharpie how large a mark do you usually make? All suggestions welcome.
