Ring necks will lay 1 egg every 1.5 days, 50 to 65 eggs per season as long as you gather them every day. the last two weeks of the season the fertility will begin to drop. feed is important as much as stress, they will stop laying if they are stressed. books you read will tell you 7 to 10 hens per rooster, for me I have had the best luck with 11 to 12 per rooster. the hens take a pounding and only need to be breed once every ten days. The roosters will take the feathers off her back and if they draw blood it will be all over for her. blinders will help with the roosters and there aggression and it does not affect the breeding. provide lots of cover, vegetation will go quickly in your pen so buckets, barrels cut in half with cutouts any thing more permanent yet easy for you to gain access for gathering. a rule of thumb I use is one bird per 30 sq. feet. again adjust depending on the amount of cover. I have never worried about grit if you are feeding a pellet, it will break down with water, and if on the ground there is plenty of grit for them. some provide grit for the calcium but a good breeder feed will have the calcium that is needed. A two year old hen will not lay as heavy I found 45 eggs was the most. and had a higher mortality rate .remember to worm your hens at least a month before breeding starts and not during. good luck JRC.
