We started raising chicks this past year, we got one batch in May and one in July. We have a batch of 30 Buff Orp chicks coming at the end of the month. What do we need to do differently with these chicks because of the colder weather? We have a stone shed that we are planning to put Rubbermaid containers in with heat lights as brooders for the first few weeks (3 of the largest containers Walmart carries). When can we start moving them outside? Will we have to give them larger accommodations inside before they can be moved outside? We are in the middle of WV for climate info.
