Hi, I'm new to owning byc's and have had one chicken for just under a year.She laid eggs just very irratically. I recently got two more chicks they are about 13 weeks and about a month ago I added them to my coop with my existing hen. They all seem to get along just fine. My older hen laid two eggs a couple days apart and that was it. I'm wondering if the younger two could be eating them or if the older one is still getting used to having other flockmates. I live in Arizona so its not cold. I feed them pellets daily and scratch for snacks. is there anything else I should be doing?
