I just got these bantam cochins about a month ago, and they are leaving the coop during the day, and going to bed at night, but all day long I never see them go back into the coop to eat. They are in spacious run with a sand floor, but I do not have food outside unless I give them a treat. They seem to get up the ladder fine when they go in for the night. Today when picking them up, they feel like they have lost a lot of weight and I am starting to get worried. They are about 6-8 months old and on about 50% chick starter and 50% Layena since I an switching them over. Should I have to give them food outside, or if they are really hungry, should they know to go in to eat? If I go in with their regular food in a scoop, they are crowding all around to get to me. Several of them are very expensive SQ birds, so I especially don't want their health to go downhill. I think I am going to switch them to Kent Finish which has a higher fat content for the winter, and since they are not laying right now anyway. Advice?
