Born yesterday, after the lemon and the Maran Bantams had sat together for nearly five weeks on two giant goose eggs. We watched, now and then during the afternoon, as the goslings emerged slowly from their shells. Yesterday they were dark and shiny, today they are yellow and fluffy. Amazing!

Just an idea but if you have a broody goose sitting on eggs then when she not looking you can sit them under her and she may then bring them up but keep an eye incase she rejects them if not sure the chooks will do a fantastic job just make sure they have a cat litter tray with water for them to swim in đ
