Hi, so I have 6 chickens. 2 Speckled Sussex, one Americana, two campines and one production red. I am a little confused cause they where all laying pretty good ( except one of the campines that I think is older) but then they slowed down in summer. Only the production red and Americana have started laying again. I know they are not laying elsewhere, cause we have locked them in the coop for a couple days. Any help would be greatly appreciated!!
