Hi everyone! I'm new to Guinea Fowl and would like to start raising them for their bug control and watch dog tenancies (plus I've seen them before at other farms and they are hilarious to watch!) I was hoping to free range them after they are old enough but maybe provide a little shed of some sort to keep their food and water covered. I don't have very high hopes of them sleeping in a shed at night as we live on 25 acres and have woods behind the house with lots of nice tall trees. I have a large coop and flight pen for peafowl and a few chickens but I don't really want to put the guineas in with them as I don't want to overcrowd my peafowl and the peafowl do not free range. My question is .. do they require a heat lamp and substantial care in the winter? I live in NW Ohio and the winters here can be pretty brutal with the wind chill sometimes taking the temps below zero for extended periods of time. How hardy are guineas?
