No eggs for 3 weeks?

[crchicks]

So about 3 weeks ago my silkie and Wyandotte started laying, they layed their first egg and haven't layed since then. At the same time I have an Ancona that's just over a year old. She usually gives me an egg every other day and I haven't gotten anything from her since the other 2 started/stopped laying. I have 2 coops and my girls in my other coop are laying just fine. They aren't broody and they're all acting normal, no signs of molting. I'm in Texas so I was thinking it might have something to do with the heat but I'm not sure.

I think it might be. My Ancona (also about a year old) has been laying spotty lately, and usually she is very regular. The same with some of my other birds. The only thing I can come up with is that it's the heat, as nothing else has changed and no one is ill or molting.
