I have seen some close to that. When I was doing research at the Bluegrass Army Depot in Kentucky, they had a sever overpopulation problem. I often saw large herds at salt licks during the summer and in the evergreens during bad weather in the winter. It was not uncommon for me to see 50+ deer in a field at a time, sometimes a lot more if the conditions were right. I think they have thinned the herd a lot now.
