If it were me, I'd do the calcium directly to the 2 hens in question and stick with all flock. I'd just grab those 2 girls at night and treat them right off the roost. It'd give you a good opportunity to look them over thoroughly, too, just to make sure there isn't anything else going on.We were feeding layer until I caught the babies (5-6 weeks?) chowing on it and since a majority were molting and/or not laying we thought to switching for a month would be good. We started with layer in the run and all flock outside but that didn't work so then half and half but that was a pain so just switched all together. That bag is nearly gone now, thoughts on what to purchase next week? And the silky is in the nest box currently so we shall see what she lays![]()
