I have 15 RIR hens, Barred Rock hens, and 2 RIR big boys. They all get along just fine. Roosters are not aggressive. A few hens do so some pretty good rooster damage...but otherwise healthy. One of the RIR hens decided to sit on a clutch. Well today a see a lil baby chick peeking out from under her! The coop is plenty big...she is in one corner--under the community nest box mounted on the back wall. Anyway, I'm. It sure if I am sposed to do something or just let em be. Concerns...I don't have any chick crumbles. Only layer pellets and then gamebird feed for my quail...I think it is medicated though. My feed store is closed tomorrow. I think TSC is open though. And the baby chicks ant get to the waterer, ao i need to do something there Other concern is the other chickens...are baby chicks safe in the coop w everybody else? I do have a 3x8 brooder I could move them too. If moved...put mama in there w em? Plenty of room in the brooder. Long story short...I searched first, but didn't get a real clear answer as to what I need to do. Thanks in advance all! Oh...I get home...and I got quail hatching in the incubator today too! Big day on "The Farm".
