Yeah, one of my other silkies was plopped down on the eggs today... she decided she wanted to lay her egg with the others and moved my setting girl off. Luckily they were all still warm and I switched my mama hen back.
Keeping an eye on them at least 6x a day. My husband and I talked about moving her out of the coop, but the backup coop is cold and its an open walled tractor coop that's going to let all the weather and cold in. Its only good for summer and not for a setting chicken.
So if it happens again, we may need more options.
We're on day 9.
