Hi fellow guinea owners! I have a hen sitting close to the house on about 17 eggs and another hen missing. Will two hens sit on different nests at the same time or have I lost her to a fox? I have never had a hen sit before as my dog has worked out how to crack into the hard shell. Yum yum. Very nervous but excited. Should I gather the keets and take over if they hatch or leave meets to it?
