we have 6 chicks, about 2 to 2 1/2 months old, they all came from the same farm. We have had them about 3 weeks. They have a coop that we built, with a lower platform, 2 nesting boxes above and a perch even higher than that. there is a door and a window. (is this big enough) under the coop we keep their food and water. at night we have been closing the door and opening it in the morning. they spend all day outside in a fenced area (but low fence, we're finding that they have been flying over the fence, perhaps on accident because they seem to want to get back inside with the rest of their flock. we will wait until they are bigger to see if they can still do this once they are heavier, and if they can we will trim their wings). their grazing area includes our summer garden which we are not using now, and has some low trees and bushes that offer cover, plus their coop door stays open so they sometimes go inside there to nap. they have found a few places they like to take dirt baths too. we plan on rotating their grazing area according to our garden needs. we're giving them our kitchen scraps (veggies, fruit, egg shells, grains). we live in a neighborhood where there aren't many preditors (except cats right now but I am assuming once the chicks are larger the cats will stay away, and after some shots of the hose the cats keep their distance). One question is once they are bigger, do we still need to close their door at night? Our winter temperatures do not get very cold, but if it is going to get down to freezing we could close the door and maybe cover the coop with a tarp or something? any thoughts? suggestions? Thank you! we're very much enjoying them and it seems they are very happy as well.
