I'm free feeding them layer pellets mixed with about 30% cracked corn, some oyster shell and some grit. They always have water available and I feed them whatever kitchen scraps the chihuahua doesn't eat. I have put a light out in their coop and its been up for two weeks as of this weekend past. It's a 100 watt bulb and its on from 5am to about 10pm four days of the week. On the days when I don't have to get up at the crack of dawn, I turn it on a couple hours before dark and leave it on until around 10. (I'm planning on getting a timer but haven't gotten around to it yet.) My hens consist of: 3 ameracaunas, 3 barred rocks, 1 white mystery hen, 1 silver-laced wyandotte, 1 phoenix, 2 gold-laced wyandotte, 1 Sicillian buttercup, 1 new hampshire red (I think), 1 naked neck, 2 naked neck/silkie crosses, 2 blue cochins pullets, 1 sebright, and one or two more I'm forgetting. I haven't gotten any blue eggs for well over a month now. There a couple in there that I don't know of ever having layed yet (the 2 blue cochins, the 3 naked neck or crosses, and two others). But most of the others I'm sure have layed in the recent past. It doesn't look like more than about two birds are molting, but out of all of those hens, I'm only getting one large brown egg and one small brown one a day. What gives?? I'd love to hear what you all think I should do.
