Electric poulty netting for big 2 month old goslings-not so much. Tried it last night and this morning they were all busted loose. I think in the dark, they got startled and like a stampede of bulls bulled there way right through it. Thinking it may be okay to contain them during the day but maybe does not make them feel secure enough at night. They don't seem to have gotten much sleep-they were all sleeping in the grass today. emotionally traumatized.
