I just got these 2 new hens. How do ya tell if they are skinny? They are RIR. They feel lighter and are more bony they my Orpingtons and Astrulorps. They also seem to want to hord around the feed bin. They go out and pick some....but come right back to the feed and constantly seem to want to eat that. I know the people I got them from only feed once a day. How much I don't know. But mabey they are not used to have the food supplied all day? Plus I did see one wait till another hen laid an egg and started to peck at it as soon as it was avaible. And I did find a Broken one earlier, I was only gone for about 30 min. Can I give these 2 hens a supplement of some kind? Or just give it time? Any sujestions would be great.
