Can anyone help or give advice...our girls are just coming up 1 yr in mid April. They laid pretty consistently all winter with a timed light in the coop. We have 3 Columbian Rockx's. In the last 5 days we've had no eggs at all. They are eating and drinking normally and foraging a lot. We have a fully secure run and coop that they are locked in at night and during the day an are that is large and fenced that they range in. We've also just discovered we have rats in the shed/coop eating food at night so we set traps (in the shed) and started bringing the food in at night. The cease in egg laying started before we found the rats... Any thoughts!?
