Get some quotes from several handymen or ask the local feed store who they have visiting their business that has had their coops built by someone else or ask relatives or neighbors who they use for handymen. Some shed companies like Tuff Shed will come on your property to assemble their only coop model for you (not cheap however). Ask, ask, ask around otherwise you'll never make any progress. Someone got a Rubbermaid small shed like 4x6 and added raised nestboxes inside as their coop and got the shed model with a window that opens for ventilation. We used a couple Kidz Homz storage bins for our first nestboxes (washable/stackable too and open at the front w/attached lids).
I researched for several months just to get the breed of hens I wanted because not every contact made by phone or email will respond back so be persistent to ask/shop around if you have the energy to do so. Just be aware that keeping chickens (even just 2 or 3) will cost more to keep then the eggs they return but if you are having hens as therapy chickens they are the best no matter what the cost to keep them -- maintenance products (lice/mites), feed, treat foods, fresh produce, dust-bath area, etc.
Ducklings like Welsh Harlequin are on the smaller side about 4 lbs and somewhat calmer and quieter then say noisy Pekin ducks and WHs are good egg layers (somewhat larger eggs then chicken eggs if that is a consideration). So many options w/ poultry. The most concern w/ any poultry is to have them in a secure coop/pen from the type of predators in your area. For us city Raccoons, Oppossums, and stray wandering neighbor dogs are our primary concern. We have our coop on a paver stone patio to deter digging critters and we have a dog kennel run that can't be torn apart by nimble 'Coon paws.
I agree about the Chinese crappola! Too many reviews say the pieces don't fit together right, poor instructions, many parts come missing or wood is cracked, etc, plus the little coops are so flimsy a big predator can easily tear a wall off to get at the hens. Many owners have enclosed these smaller coops inside larger fortified runs like dog kennel chainlink or powder-coated wire walls or hardwire built pens w/roofing.
I sincerely hope your DD will have the chance to care for some pets. GL!
