I have three male and 5 female Buffs and 2 male and 2 female Wellies. The numbers were supposed to be 10 female and 2 males but the chicks had different plans, lol.
They are actually getting along fairly well at this point. Not as tolerant of one another as they once were but then they are maturing. Given their cramped brooder/cage conditions I'm pretty impressed that blood hasn't been drawn yet.
The coop is a little on the small size given the ratio of hens to roos. 4X8X4. But I had already began construction thinking I had two roosters and 10 hens when suddenly the two Wellies decided to grow in black chest feathers and grow combs and one of the Buff hens grew a comb and wattles.
I will probably have to enlarge by fall but at the moment I'm planning to put up a 10X18 foot run made out of kennel panels and hot wired for predator protection. Since they will only be pinned up at night and have been offered plenty of roosting space in the coop, I'm hoping that the extra run space will give the the square footage that they need. The coop has been built inside our barn and part of the run will also be under the barn's overhang so they will be able to get out even in nasty weather if they want to. And since I set the main coop 3 feet off the ground I have space down below to add a chicken condo if I need to...and probably will have to all things considered.
I'm planning to post a pic once I get it painted. Believe it or not, I have spent the grand total of somewhere around 10$ on this coop. We had all the wood, posts, etc on hand from other building projects and the money went towards nails. I promised my husband that the chickens would not cost us an arm and a leg so I'm pleased that I've managed to keep my word to him.
Just an FYI, we had a 75w black light on overnight in the coop and the temp was 55 this morning. Looking for a higher wattage light bulb to see if we can get the temp up a little better.
