Well, first congratulations on the baby!!!! And chickens might be a little much as they need babied at first, unless you get full grown ones.

No, we would definitely start with chicks but because of the attention needed, we obviously can't do that with a 2 year old and newborn 😂 . My wife is retiring to homestead and homeschool when our youngest is old enough for public school. We will probably get some then. An important learning experience for the children as well.
Here in Brazil people just trow some chicken there and doesn’t give attention at all
