Corrected sentence:
The hen pecks at seeds, and the chicks peep along.
Why this is better (easy steps):
- Start with a capital letter: write "The" instead of "the".
- We often say "pecks at seeds" so adding "at" sounds natural.
- There are two short ideas joined by "and" (the hen does one thing, the chicks do another), so we put a comma before "and".
- "Chicks" is plural, so use "peep" (not "peeps").
- Finish with a period at the end.
Another simple option for a young reader:
The hen pecks at the seeds. The chicks peep.
