Question

for which species would a transport carrier be appropriate to use as a handling aid? rabbits pigs poultry sheep/goats

Explanation:

Transport carriers are commonly used for handling smaller animals that can be safely contained. Rabbits are small animals that can be easily transported in such carriers. Pigs, especially adult ones, are usually larger and may require different handling methods. Poultry is often transported in crates or coops which might be different in design compared to the typical transport carrier. Sheep/Goats are larger animals and are usually handled using pens, chutes, or other larger - scale handling aids rather than a small transport carrier.

Rabbits
