HI!! We recently just joined BYC. We have a small flock of 5. Four hens (Barred Rock, Black Australorp, Manan/ Buff Orpington cross & Buff Orpington hens) & one HANDSOME rooster (White Leg Horn/ Buff Orpington cross). We had bought a used Hen house and fixed it up and did some modifications to it before getting the flock. We also built an add on which is a opened area but covered in hex wire and area of 8'L x 4'W that stands 36" in H. These birds came from a free ranging flock with a large number of birds. We just got them home on Tuesday and that evening our Black Australorp layed one egg. Now its Saturday and none of the hens EXCEPT our Buff Orpington is laying an egg every morning (some times she will lay one in the evening too). We went from having 78 degree weather during the day the last three days and then yesterday and today it is mid 60s. I have clean fresh water for them twice a day also have free choice of Layers Ration 16% out for them. Is their anything else I need to lay out for them? OR are they not laying due to the weather change and maybe stress of being moved to a new environment? I was reading that you can feed them oyster shell as an extra source of protein. Is that necessary though to get them to be more consistent? Now these are hens who had been laying before. Any opinions on what I should do would be awesome. Thanks!
