So we have about 30 chickens and I have always carefully measured out the amount of feed for them each day. They get there layers rations first thing and they are totally focused until it is finished (it sound like a machine gun in the Barn s they are all so furiously pecking) they then tend to wander about in about 3 acres of grass land scrounging whatever they can find. then in the evening they get a few scoops of mixed corn to scratch around for. I have a separate area where I have my young cockerels who are being fed growers and being watched til I decide who is going to get lucky and get a girlfriend and who is going to meet Mr Oven. Now in that house I have free access to food all the time, and they don't seem to be that fussed by the food and don't appear to be eating any more than the birds who I am carefully controlling. SO for the last few days I have given all the hens completely free access to thelayers pellets...On day 1 they totally stuffed themselves, and spent the rest of the days sleeping ...not much foraging and they still had very full crops at bedtime so I skipped the corn rations, Day 2 they came out f the night time barn very calmly this morning rather than the normal rugby scrum for food, they were all very y leisurely eating and then went of to forage without finishing all the pellets. Day 3 they seem to be eating about the same amount as they were eating when I carefully controlled it, only they appear to be eating it in small amounts through out the day. Obviously this has only been a few days but so far the egg yield seems to be about the same. I plan to keep this up for about another 10 days . Just wondering what others opinion is on ad lib feeding over controld feeding. My reasons for controlling were that I was told that fat chickens don't lay eggs and die young, so we need to control their access to the feed. However form my very short trial they seem to be pretty good and regulating the amount themselves, and the free access seems to have reduced the competition around the feeding area.
