Hi there, I have 6 Silkies, one of which has been laying every day for three weeks now, however, the last few days she has been staying in the coop in her nest box all day long? She hopped out this morning for 10 minutes and is now back in there again. Is this a broody hen? Also, if I want her to hatch her chicks, will she lay a clutch of eggs? How many is the norm for a Silkie? And wouldn't she have to mate with the rooster every day in order for the daily egg to be fertile? Will I have to seperate her from the others?
