First timer with chickens here... my Red Star is 17.5 weeks and over the past week has been squatting, holding out wings, etc. Today she went into the nesting box!!! Any advice on when I will see an egg? I was just scooping out the coop when she jumped up after looking around the coop like she wanted somewhere to go...........any comments woould be appreciated. I'm like an expectant father pacing in the waiting room.
