We are getting 6 chicks in May, and I have to build a coop before then. We are getting 2 EEs, 1 SLW, 1 Australorp, 1 Buff Brahma Bantam, and a Silkie. So, four med size hens and two bantams. I'm thinking of a 4' x 3' henhouse and a 4' x 10' run. Is that enough space for them? I'm also planning on building a portable run for them, so they can have access to fresh grass. Also, what is the best way to ventilate the coop? I was thinking of making vents on the top and bottom. Cover them with hardware mesh/chicken wire and make a plywood flap that can be opened or closed. I would open them both in the summer and spring, but only open the bottom one in the winter to keep the warm air in. Is that a good idea? What size brooder am I going to need? Is there a maximum size for the chicks? I read about 6 sq in per chick, but would they freeze if I gave them too much room. How soon can I put them in their outside coop? I've read you can put them out as soon as two weeks. Is that too early? We have a (prox.) 2' x 3-4' wood box. If we convert that to a brooder, how long will it house 6 chicks comfortably? It's about 1 1/2 - 2' tall. This is going to be my first building job ever. I have limited tools and a limited budget. I'm planning on using mostly pallets (find decent ones and take them apart) and a few studs that we intercepted from the dump, and pulled nails out of, for the wood part. We are most likely going to buy corregated roofing (any info on how to install that on a slant and make a PVC gutter system would be appreciated) and chicken wire or hardware mesh. We have old windows from replacing ours last year. I would like to build a frame and use half of a window for light in the winter. They already are in two parts, because that is part of their opening mechanism, so I don't have to do anything fancy. It won't open, which is why I'm making vents as well. Can I use silicone sealant to "glue" the window in? Thanks!
