Congratulations. You are now the rooster and they are displaying a submissive posture which usually indicates to the rooster that they are ready for mating. No further effort required on your part.... Do you have a rooster?
More of my 10 Comets are now doing the dance of submission and I have to pet them and tell them how pretty they are and that their very good girls. Been getting 5-6 eggs a day but today there were 8 including a jumbo. 71 since Labor day! So they get all the high praises and attention I have time to give them. We do like our picnic table time together.
