I made nest boxes by cutting out the front short end of a rubbermaid tote. The lids are still on, it's sufficiently dark in there, I have 4 boxes and they were laying in them at the previous rate. It's been more rainy and we've had snow a couple of times and they refuse to go out in the snow to their run so perhaps they're just annoyed with each other being in the smaller coop area (5 sq feet per bird in coop, 140 sq feet in run)? With surgery in two weeks, I can't put a roof over the run, and someone warned me against putting a tarp (because of the rain- didn't want it collapsing) over it in the meantime.
Feed is the same- Purina Flock Raiser with oyster shell mixed in. 20% protein. Occasional scratch (mostly used to get them back in their coop) and occasional kitchen scraps.
As I said, literally nothing has changed, except a couple of snow days. Could that cause it? Since they refuse to go into the run if there's snow in there?[/QUOTE
Good morning from New England. I too have RIR's that were hatched in April 2018. I put them on Purina Layena when they were 17 weeks old. The kind folks at the local feed store said that laying crumbles contained the nutrients the pullets needed to be healthy while they were producing eggs. I supplement with leftover vegetables (no added salt), oatmeal, and apples. They also get meal worms and a handful of corn before "bedtime" on cold nights. I'm getting 4 eggs a day from four pullets. I have one pullet that I'm pretty sure is not laying yet. So, is Purina Flock Raiser meant for laying pullets and hens? And as far as the weather: we've already had temps in the single digits at night and that did not impact their laying.
