I have 15 almost 3 week old chicks in a big rubbermaid container. They are eating like crazy and draining their water almost as soon as I can fill it. I'm debating putting them outside during the day in a wire dog crate (the weather is in the 80s) and then in our garage at night with the heat lamp. Of course, if we have a cool day I would leave them inside with their light. What do you think? If they are on grass (the bottom of the crate is wire) will they need grit? I'm assuming yes. They just need a bigger space because they are jumping on top of the feeder/waterer. I have a screen on top, but they are just growing TOOOO fast! Any thoughts?
