Currently...mine covers almost almost the entore heighth of the brooder....covering the second from top slates which is where the one almost got out yesterday...
Id start higher as long as its breathable fabric, or hardwire cloth. You can always adjust the fabric/net down
Eta... i also tuck...
Most definetly can. I had one get out and get pecked to death!!! It was heart breaking.
I thought i had it covered..but they got through the bars and under the net...
They are a wk and half now and still can fit through them....
Current set up with the net...yesterday i pulled the net...
