Hi everyone, over the last month my hens have been through some pretty traumatic stuff: first, there were too many roosters who were abusing them, their coop was not properly cleaned and there may have been some sick chicken, and then to cap it all off a very aggressive dog strolled onto our property and killed 6 (they are free ranged) while the others ran for their lives. We had been noticing an egg decrease for some time, but after that they went to 0. Afterwards, we dispatched all roos but one, cleaned and disinfected the coop and switched to sand litter, moved their nesting boxes... and nothing. It has been two weeks, and no eggs - just none. We have about 8 laying age hens and about 15 more who should have started laying by now (they're at 18 weeks now). We are unsure what to do. We could give a course of antibiotics to attack any lingering disease, or maybe the stress has simply proven too much and they need more time to recover. Ideas?
