So we have 5 hens (a rhr, buff orp, barred rock, blue laced red wyandotte, and an ameraucana). We have had them for 31 weeks so they are between 31 & 32 weeks old. We only have one laying at the moment. Here is my question/issue. Our red is our only layer and has been doing so for 7 weeks now. We get about 6 eggs a week from her. Last week I went to check on the girls and she was in the box doing her thing so I left them alone and came back later. She was finished but my buff was in the same box and looked to be doing her thing. When I went back later there was only one fairly large egg. So it seems that the buff was just sitting on her sisters egg. Then today I am home sick from work (we are in So California so no snow storm) and heard the egg song. I went out to the coop and the only one inside is my buff singing away. Again it was another decent size egg. Is it possible that she is sitting on her sister's egg and thinking it is hers? Or is she getting ready to lay herself? We are very impatient for someone else to start laying.
