Heres a few pros in my opinion, and
@Duck mommy 2019 may be abel to offer some insight as well.
Pros:
- You don't have to worry about as many egg issues, because they don't lay nearly as often. Then, your parents wont have to pay for expensive supplies and antibiotics, that come with eggs issues.
- Often, adopted older chickens are free, your parents wont have to pay $5 a chick, or 10$ for an adult bird, which can be expensive after getting 4 chickens.
- They are older, so won't live as long and aren't as much as a commitment, as a chick that will live for 14 years. Instead, you only have a 4 year old chicken for another 4-6 years.
- They already have an established flock together. So instead of worrying about chicks pecking each other to establish the pecking order, older hens that come in groups, already established there pecking order.
