I live in Massachusetts and this is my first year with chickens. I have 10 total chicks, 3 of them are 6 weeks old and 7 of them are 3 weeks old. I have read many posts on HOW to move them outside while lessening the heat lamp but nothing on what the constant temperature they can move outside (or what month, which would be most helpful). They're outgrowing their box and as much as I enjoy them indoors, they're taking over my living room! Is there anybody on here from New England (since you're familiar with our weather patterns) that can assist me on which of these spring months I can move them out to their pen/coop area? Is it too early for them right now?
