Lol I tried doing the same thing a couple weeks but with leaving them outside at night and they want no part of it! My hubby heard them crying and asked if I was killing them so I figured they can stay inside till aug but I told them the first week of aug they are outside! I really wanted some time between the 3 batches of chicks without having the brooder/play pen taking up half of my back room but it isn't looking too good. Oh we'll I'm sure once everyone is outside I'm gonna miss having someone in the house..
