Is there anyone out there who can shed some light on egg laying necessities i.e., required temperature, light cycle, optimal feed ration, effect of molt, laying cycles, etc. for laying hens in winter months. In terms of anatomy, what should the vent look like on a laying hen? Are there any other experiential tidbits that might expose a hen as off duty? Please feel free to go into as much detail as possible. Slainte mhath!
