This may have been on this forum before, however I have not found it. Don't know if hens have stopped laying because of the heat or if they are getting better at hideing them as they "free range" in our big yard??>
I never know why my hens decide to stop laying. Some people have felt that extreme heat has caused a drop in production. I recently remodeled part of the barn around the chicken coops which resulted in fewer eggs for a while - partly because they were laying them in odd spots, partly because they were annoyed (?) or perhaps because it was extra hot at that time...I never can outguess the ladies.
Its that time of year when they slow up due to molting and less daylight.If you want them to continue to lay after the molt then you need to provide them with a light.They need 14 hrs of light a day.I put my light on a timer to come on in the morning at 4am.You can have it on a timer to come on a few hrs before sunset and then again a few hours before sunrise.Don`t have it turn of when it is dark out as they will not be able to see to get to the roosts.
