Okay, I went out to the chicken coop today, and I looked in the nesting boxes and on the floor as always...but today some stuff was different. In two of the nesting boxes, it looked like one (or two) of the pullets had kinda scratched out a little bowl-shaped hole in both of the nesting boxes' shavings, and they normally NEVER mess with the boxes. Also, under the boxes, there was also another little bowl-shaped hole dug in the shavings under the boxes, and one of my pullets was kinda walking over to it every once in a while (not anxious or anything really), and also looking up in the boxes (which she NEVER does). Could one of them be getting ready to lay!?!?!?!?
