Then using a pvc cutter cut lenghts of pvc to make a box the width of the netting. and how ever long .... For fifty chicks I would make the whole thing about eight feet long. I usually do quick construction like this with materials that are the size as you would buy them.
PVC cutters are a quick way to cut the pipe and You dont even have to glue the pieces together.
PVC pipe can also be cut with a hack saw or a miter saw, one or both might already exist in your house. I watched a couple of you tube videos of PVC pipe cutters (never used one), I'd stick to the other options if for no other reason than I wouldn't have the hand strength to squeeze them through many cuts and most looked to work quite poorly on the 1" pipe he was using.
- If you have a miter saw, make a short pencil mark where you want to cut. If your saw is power, put the mark on the pipe under the blade and done in 2 seconds, no strain at all. If it is a manual miter box, the slots in the box will keep the saw blade straight, saw away.
- If you use a hack saw and no miter box, the easiest (and CHEAPEST) way to make sure your cut is straight is to wrap a piece of paper as a guide around the pipe where you will cut it and draw a line all the way around with a pencil. That way you can see if you are going off on an angle. Hold the pipe on a table or other comfortable height flat surface with the pencil mark hanging over a couple of inches and saw away.
BTW, pipe comes in 10' lengths so if you make it 10' long, you have fewer cuts to make. If you make it 5' wide, you only need to cut one piece of pipe in half. They even make 3 way fittings so you can make a corner with a vertical post using a single fitting. 3 cuts on a 10' pipe and you have four 2 1/2' 'wall' posts.
So a brooder 5' x 10' with 2.5' high walls - 4 pieces of pipe and 4 cuts. If you need intermediate bracing across the 'box' AND a vertical post at that location, they make 4 way fittings! Of course you would then be cutting the 10' long sides everywhere you used that fitting.
