Hi all! I am a first time chicken owner. Right now I have two four month old mix breeds. I think they are four months old. The guy at the feed store said they were about a week old or so . If that is true that would make them around four months old.I have a few questions I hope you can answer for me. I understand they will start laying around 5 months of age is that right? I started out with four but through a night of being left outside unattended I lost two. It was a sad, learning experience. I'm getting three more day old chicks in a few days which leads me to my second question. When the new ones are old enough how do I introduce them to the older ones. At what age should I do that? My last two questions have to do with egg laying. I heard from a old farmer that you should always leave one egg in the nest so they will keep laying. That doesn't sound logical. Is it? Last but not least what should I be feeding my girls?They free range at least two or three hours everyday. I wondered if thee is food I need for when they are laying. Right now they are on the starter chick feed and people food I give sometimes. Thank you for any responses I get.
