18 day old chicks in the brooder can already fly. They usually only get 3-4" off the ground to do that 'touchdown!' chest bump, but today one got a good foot up and out the brooder opening while I was cleaning up. They're in a garage (thank goodness - I hate to think if they were in the house) and I caught her with some maneuvering and a window screen to help corner her. The others won't be far behind - and I'm thinking that they should all be clipped at the same time to keep the pecking order. Only 7 chicks, but that's a lot to chase around my garage Help from those in the know would be greatly appreciated.
