I recently got new 1 year old hens to go with my 5 month old hens. They are all getting along now, but the new hens aren’t laying eggs like I was told they did before they got here. It has been about 2 weeks since they have been here. Should I be concerned that they aren’t laying? They are eating the grower/finisher pellets that my 5 month olds are eating and I’m giving them oyster shells for extra calcium. I need to switch to laying pellets, but just need to finish out my other. Any thoughts?
