The side walls (BS_K0064) that come standard with the quail cages (BYK series) do not have an opening. Each section on a layer is closed off to each other.
We can swap the standard quail cage walls with (BS_K009x) Middle Wall (With Optional Breeding Divider) - Hutch Style for Quail Cages if you want an open hutch style cage layer with the option for closing sections when breeding. There are 2 walls per each 3-section layer.
Please contact us before placing the order online. Please call us Monday – Friday 10:00 am to 6:00 pm ET at (800) 511-1369 or email: email@example.com to get the swap out fee and reduced product cost.
