Hi I am really excited today because I believe one of my two hens is about to lay. She is hunting around but every time she goes in the house the other hen follows closely behind followed by the rooster. They have always been close. Will this put her off? How long can she hold onto her egg? Should I try to separate them? any advice appreciated I am a novice. Thanks. ps she has been doing a submissive posture everytime I stroke her for at least a week.
