Hello! WELCOME!!! I'm so glad you decided to get baby chicks! Watching them grow up is so special!
I did SO much research before we got chickens, so I have many facts.
In that picture, you have about 20 chicks, right? If so, you are going to need a bit of a bigger brooder. Baby chicks may be tiny at first, but they
grow very very fast. Once they get to be about 4,5 or 6 weeks old, they will be wanting OUT. They flap and attempt jumping out all the time.
(because of their boundless energy, I would recommend introducing a poultry nipple waterer soon. It prevents them from dirtying
their water.)
Anyways, there are SO many threads on BYC that you can look at. Food, temp. for the brooding light, when to transition them to a nice coop etc. With so many new members of the family, it will be a lot of work, but you can only try your hardest to give these chicks a great life.
PLEASE ASK MORE QUESTIONS IF YOU HAVE THEM!!!! GOOD LUCK!!!!
(P.S. with so many chicks, when you move them to the coop, that coop will need to be large
)
