I have some similar looking hens, that are supposed to be RIR crosses with New Hampshire reds, that are also supposed to be sex links...... (sound fishy?) I think they are production reds, and are probably part golden comet. That coop is tiny and probably could keep 2 happy BANTAMS! The best chicken coop that I could find online is the Eglu go up thing, and it’s a little expensive and takes FOREVER to arrive, there are lots of run less coops but almost all of the online coops that have runs are said to be way to small as well. I personally bought a big dog run to attach to my shed like coop, built to be a coop, have any sheds you can put them in? Even if they can’t be outside at the same time I have a feeling they will be happier.
. This evening I plan to be super sneaky and when they're all in the run, block the door with something and take the food and water (and eggs?) out. Then when they're all in to roost, block the door again and fix up the run. Also add the refilled food and water to it, as well as the grit and OS. I was outside with them, then it started raining. My roof seems to be working, which is good. It does look like they've figured out the dust bath, as there was a chicken sized hole in the dirt when I got home. You guys are right-they do look like red sex links.
