Okay, how do I know if we are getting close to egg laying? I have 3 pullets, one with a red wattle (barred rock) at 18.5 weeks old today. One (welsummer) I'm sure is nowhere close, and I have no idea when EE's start to lay. But the barred rock seems...well a little bit different lately. All three are hanging in the coop much more than usual (but it's not hot or cold out), and at least one of them is creating mounds of pine shavings; digging all the way down to the floor. Are they trying to make a nest? I covered up the nesting boxes when they first went to the coop because they were sleeping in there. Is it time to uncover? Stick some golf balls in there? I have been feeding layer feed for a few weeks now & just bought oyster shell. What else should I do to prepare? I'm so excited!!!! Thanks!
