Hi, i'm planning on hatching Bobwhite Quails this Spring, i just wanted to get your opinion on the pen size i'm preparing for them. The pen size will be about 10ft long, 3.5 ft wide, and 1.5 ft high. I'm looking to fit maybe 5 to 7 birds in this pen which will make 2 trios. What do you think, could i put more birds in the pen? Thanks I appreciate it !!!!!
