My 2 sex links are around 15 weeks now. Is there any certian behaviors to look for to indacate they are about to start laying? One of my girls has been acting off a little. She has been laying in fluffly spots in the yard and not getting up for about a hour. She will even watch the others fight over bugs and not even move sometimes. Then some times the flock will be in one spot while she is one the other side of the yard by her self sitting. Then other times she's with her flock as normal. Any clue as to why she could be acting a little crazy???
