princess fiona wanted a flock of backyard chickens but there was no good place in her yard for them to live.

Explanation:

The sentence has two independent clauses ("Princess Fiona wanted a flock of backyard chickens" and "there was no good place in her yard for them to live") connected by "but", which is a conjunction. When two independent clauses are joined by a conjunction, a comma should be placed before the conjunction. So we add a comma after "chickens".

Answer:

Princess Fiona wanted a flock of backyard chickens, but there was no good place in her yard for them to live.
