I have a couple quail I got a cage to keep them in the garage for the winter on lights hopeing to get some eggs. The thing is that they are now 3.5 months old and no eggs? It is very cold here? Do they also need heat?Here are pictures, are they not ladies? One has started this new call in the morning, sounds like Lightning Mc Queen in the Cars movie when he says "Ca chow"! Just want some eatin eggs? Any advice would be great!
