at 14 months they should be laying regularly through winter. This would be their first winter they would be laying.Thank you for all your help and recommendations. I didn't really notice any weird behavior, but I am watching this one very closely. They were 14 months old (roughly). They haven't really been laying eggs but I assumed that it was because of the winter and the shorter amounts of daylight (I was told they need 14 hours of daylight to lay eggs). I am going to go to the feed store tomorrow and see what kinds of medicinal products they carry.
Thank you again for all your advice! I really hope I can save my last girl!
If they are not laying, I'd be concerned. My Red Sex Links (just like your avatar picture) lay consistently. Every day. Miss a day every month or two. If your hens aren't laying that well and that is what they are (red sex link) they may have something like worms, or not eating proper feed.
What type of feed do they get on a daily basis?
