So my husband is building a brooder for my son's kindergarten class (they are hatching a dozen eggs) and we grabbed this design http://4hembryology.psu.edu/broodern.html off the internet but if you read the instructions things though you will see that it goes terribly wrong. The pictured brooder and the instructions don't match. So I wanted to ask a few of you folks who have built brooders or who are handy contractor types to chime in on what else might be wrong just in case we aren't seeing something else of importance. Please don't recommend starting from scratch with another design because my hubby has already invested in this design (cut the boards etc.) and will likely completely blow a gasket if I tell him we need to start over so what I am looking for is advise on how to use what's here but make it work correctly. If that's not possible, let me know, as I don't want any little chicks to suffer because we built a faulty brooder, but if we can make this work, that's idea. So far we have figured out that the top has to have an additional 3" board across the front to support the plexiglass and the heat trap. The placement of the lightbulbs looks dodgy to me but I don't know much about all this, so I am hoping someone can look at this and say, here's what else you need to keep in mind. Right now we are going to: a) add a 3" plywood board across the front top to create support for the heat trap, plexiglass and hinged plywood top. We think we need to create a frame for the chicken wire that is across the other half of the top. Is there anything else about this design that looks vastly wrong or dangerous to chicks? Thanks for any help!
