My hen has been setting for 3 or 4 days and done very well but lastnight she lost her nest probably when the light went off and she ended up on another nest with no eggs.......... ;o( Her eggs were cold, but I put her back on them anyways, will they still be ok or should I swith them out for new ones? Or will she not set on them long enough if I do that? HELP! I didn't want to fence her off but I guess I will now if it's still worth her setting.
