Obviously you are going to do what you want, but it’s my understanding that bobs should be kept in pairs or same sex groups in a ton of space. if you have 2 pairs you need like 50+ sq feet. Also, just because you have 10 and 10 doesn’t mean they will pair up happily, there will be popular mates that others fight over. Your gentle cots will also be targets. No matter what we all say to you, you just come back saying the same things. So do what you want, but 20 bobs and 6 cots in 60 sq feet will be a blood bath. I started quail many months before you, I keep a lot of birds, I research constantly, and I still feel I learn new things every day. You seem so eager to get new birds that you’ve decided you’re already an expert on the previous ones. I’m done commenting to this post as it seems like it’s more of a hey I’m doing this post, than a please give me info post. I hope you beat the odds, but don’t be surprised if the worst happens. If you want bobs my suggestion is to get them their own enclosure, and keep just a couple happy pairs.
