Supplemental insulation can help here. Ventilation is really important, but I have noticed that really limiting it to a slot or two on frigid nights helps to add a few degrees to the coop.
Frostbite isn't a great thing for hens. Firstly, it's not a great sign for their health and likely...
There is certainly no need for heating, unless you have chicks which would be highly unusual. Chickens are extremely hardy and need to be kept away from drafts. As long as you have a coop that blocks draft, the hens will be just fine. I tend to think the benefits of a heat lamp in a wood...
Very formative time for your hens. At that age, they should be kept on crumbles and transitioned to pullet feed to prepare for egg-laying. Scratch isn't really something that can supplement as feed, unless it is homemade and essentially the same as a crumble/highly nutritious feed. It might...
It is definitely a gourd. Could be heirloom, depending on where the seeds came from. Edible, but also decorative if you have no interest in it.
Not bad for a random plant. That produced some great gourds for you!
Those are duck eggs. The dirt on them alone is an indicator without even considering the size of the eggs. I know duck eggs are usually much dirtier than chicken eggs since they prefer to lay on the ground.
Chiming in - Not really possible. If anything, a multi-egg situation would usually result in a deformed or clearly enlarged egg. I've never had any experience where a hen laid two normal eggs in the same day, let alone one sitting. A few other birds got in there and laid eggs.
I've always gone month to month rather than bag to bag, simply because I don't control how much feed I provide on a consistent basis - I always just make sure that the feeder is full. Some weeks the hens eat more while others are less. Over the course of the month, I'm able to determine cost...
I averaged 10-12 eggs a day so we usually gave them away to neighbors, friends and family. There are a variety of uses if you find yourself with a surplus for you to try:
-selling locally
-egg heavy dishes (i.e. French Toasts or Frittata)
-donate to food bank (some are picky and want to know...
