Hello, It's been a little over a week now since getting our 6 chicks- they're doing well and seem to be growing FAST. Brooder box is a large 2'x3' sized plastic tote with high sides which seems to be doing the job- although I did cover it yesterday with a section of metal screen when I saw one of the chicks standing on top of the water bottle looking over the side. I feel like they are (or soon will be) outgrowing this set up. I like the plastic aspect of what I'm using now as it's easy to clean and can be set on a table. Any suggestions out there from the experienced chicken people?
