We just started with chickens this summer. I've found we are getting more eggs in the winter then we did in the summer. I think ours like the cooler temps. I guess when it stays around 100 degrees they give up on egg laying.
I used to get 5/5 daily from my 5 white leghorns. Now the last three weeks or so I get between 1-4/5 day. :-( I havent had a five egg day since before Christmas!!! They dont love me anymore! MAybe bc I didn't get them a Christmas gift and hatched their babies that day instead?!
