Some clarifying questions:
How long have you had the seramas?
Was the rooster aggressive before you brought in these new birds?
How long has he been aggressive?
Correction: The size of my run is similar to the size of yours (possibly a little bigger), but the area the chickens have access to at any given time is half that size.
Heat lamps are the most commonly used heat source, but I strongly recommend against it. No animal, but especially a developing baby animal, does well having light 24/7. Neurologically, they really need darkness at night. There are some good non-light heat sources out there.

I disagree with others about your coop size. You live in a place with mild weather. Your birds won’t be holed up in the coop for months of snow, ice, and sub- freezing temperatures. All they really need the coop for is to sleep in and lay eggs in. The rest of their time can be spent outside. The...
You can get a no-crow collar. They don’t actually keep the rooster from crowing, but they make their crows quiet. I made one for my rooster out of a 1” wide 10” long (my rooster’s big) piece of velcro. It works like a charm. You can buy them on Amazon too. I just wasn’t satisfied with the...
Quick clarification: If you buy any eggs from the grocery store (in America at least), DON’T leave them out on the counter. Eggs have an anti-bacterial coating on the outside, but grocery store eggs are washed and that washing removes this coating. So, grocery store eggs would not be safe to...
I have found that dating makes sure I eat the oldest first and don’t risk accidentally leaving any eggs around too long. I date an old carton with the date I collected the first egg in the carton. It’s an easier way for me to date them.
If you don’t use air conditioning, shelf life of eggs...
I have a flock of 3 barred rocks and 5 black australorps. The barred rocks have had their bird brained moments, but the australorps are amazingly stupid. They’re so dumb I actually worry that they’ll get themselves seriously injured or killed. Two of them (or maybe the same one twice) managed to...
My chickens get a lot of free produce scraps from the grocery store. I put these scraps in the compost pile they have access to. They eat greens, fruit, squash, etc. and leftover scraps of other things from my kitchen (oatmeal, cheese, meat). They also eat plenty of grubs and bugs out of the...
