So I have 8 laying hens together in the coop with attached run. They are all known to lay eggs and have been laying for a good 5 months now. The problem is that they have never been on a regular schedule with laying. Right now, I am only getting 1 egg a day ( 2 if I am lucky). Some have stopped laying completely. I am feeding the plenty of laying pellets, oyster shells and plenty of fresh water. A few weeks ago they all seemed to have some sort of respiratory problem so I treated them with Duramycin and while they were taking that, I got 5-6 eggs a day (Of course I couldn't eat those). They seem to be over the respiratory thing, they are eating well, poop seems normal. Anyone have any idea what I can to do get them to start laying better? Or maybe just help some of the ones who have stopped to start back??
