So...about vitamin D. I have both 5,000iu and 10,000iu gel caps of D3. Which one, and how many of those would I break over and mix in with some oatmeal for my dozen girls, and how often? I really want to help them, clearly if 2 of them have simply stopped laying while not being broody for the last couple weeks, there's a deficiency somewhere. It seriously happened right around the time the sun disappeared. I hope I can use what I have already, I've got TONS of D since I'm also very deficient and take so much through the winter. Thanks for the help!
I dose 1,000 au per chicken once a week in winter; I'll probably be giving Sylvia twice that a couple of times a week before I start moving the other BLRWs in with her after Ian's gone.
The big deficiency is daylight, and especially the rapid decrese in daylength: last year, between Halloween and Thanksgiving I got, at most, five eggs all together and then starting about then and increasing every day until they hit Spring and I got buried in an egg a day from everyone for a while, I started getting 3-6 eggs a week from all of the hens; tghe EEs started laying while they were still in the hall bathroom with no where near enough light. I'm trying to pick out the metabolic path of how much of the light thing is lack of Vitamin D metabolism and how much of it is related to the lutenizing hormone pathways that control ovulation and are, typically, sensitive to both light exposure and body fat content across species.
I need to google a whole lot more and possibly find some poultry science articles not done by Tyson/behind pay walls.
