I have 10 total hens that are just starting to lay in the past four weeks. One of my Amer. was the first to start laying. We got 3 or 4 eggs from her in the first week. In that week we had one more hen start laying as well. I would now say I have at least 7 out of 10 laying except I have not gotten another egg from my Amer. since that first week. Any idea why she would have started and then stopped? I am giving them additional light, always fresh water. I have 2 Amer. hens total, I assume only 1 of them had started laying due to there only being 3 or 4 green eggs that week. The other hasn't started at all. Is this normal?
