Hi, I need some help/advice on chicken houses! We're going to have a huge walk in run built so just need a house to fit around 15 - 18 standard size chickens in. Having trouble finding one so big though! Anyone know any good websites that might sell them for a reasonable price? Found one to house 15 medium chickens on this website - https://www.chickencoopsandhouses.co.uk/Nelly-Portable-IN-STOCK.html - it has a nesting box with four compartments. If I added in another nesting box with another four compartments would I be able to house more chickens in it does anyone think? Or would it be the perch space I would need more of? Thanks in advance!
