Hello. We are so pleased to find this source of information and for sure newbies. Our facility is now finished and ready to get our stock. Our interest is laying hens (8-10) and think our best purchase would be pullets. This being said since we would be afraid of getting hens past their prime and the wait time of chicks to mature. We are unsure about whether it is best to stay with one breed. Could there be an issue that we should be aware of if we should mix breeds in the same enclosure? At this point not seeing any need to acquire a rooster since our goal is to harvest eggs only.
