How to adjust a coop for a Jersey Giant?

[StrykerSilver]

Me and my dad are getting chicks this week. In around a month, we will be adopting a Jersey Giant cockerel. Neither of us are experienced in building, so we are hoping to get a coop kit and modify it to fit the Jersey Giant. We will be keeping 7-8 chickens in total, so we'll need a pretty big coop. What modifications would we need to make for the coop? Would lowering the roosting bars to 24in be enough? Would we even have to modify the nest boxes since we are getting a rooster? I'm also a bit concerned about the entrance/ramp, and was hoping someone could give some advice.

What is this kit you speak of? Most prebuilt coops are too small for the amount birds they claim to fit. For 8 chickens you'll need at least 32 square feet of floor space (more if you're in a place with cold winters), 8 feet of roost length, and about 8 square feet of 24/7/365 ventilation placed in such a way to prevent drafts from hitting the chickens.

Lowering the roost to 24" is a good idea. I would make the pop door at least 16 inches high. I would also raise the pop door up so that a thick layer of soft bedding can be put down on the floor to cushion their legs and feet when they jump down. I don't know what the size of the nesting boxes are in the kit, but I always like to go larger, around 16 inches high. The nesting box sizes that are usually recommended are quite cramped for normal chickens.

Our plans have been updated - apparently the feed store we will be getting the chicks from sells out of chicks quickly, so we have lowered the estimated chicken count to 6. (5 standard chickens and the Jersey Giant rooster). We've been looking for kits today (they have the pieces cut to size, as well as other assembly equipment. The assembly is done by the buyer.) Here's the coop I'm trying to convince my dad to get!

Thank you for the advice.

That is what I was afraid of when you mentioned the word "kit." Not only is that coop big enough for about one chicken, the layout is very impractical for you and the chickens, and the build quality looks poor (the wood is very thin and it doesn't even have proper roofing).

You would be much better off buying a shed and modifying that.

Ah, thank you. I've only kept bantams in the past, so thanks for correcting my being off.
