I have a Leghorn, an Australorp, a Black sexlink, and 2 RIRs. For the past few weeks, only the australorp has been laying, and even then she only does about 4-5 per week. The Leghorn and RIRs are a year older than the other two, and one of the RIR's has been molting. The leghorn looks like she's finished with her molt, but this is my first time with molts, so I can't be completely positive. They are confined for most of the day, and get about an hour of freerange time per week. Is this why they aren't laying as much? Also, I'm in Texas, and the temperatures drop down to the 50s or 60s, so the winters aren't that bad. Any advice is appreciated.
