I have six ladies I got from TSC. Unknown if they were vaccinated. Is it required or very recommended. If I need to get them vaccinated how do I go about doing that. And no the staff didn't know anything at the TSC. Also do I need to stry supplementing their food with anything? I am feeding them chick starter food bought from TSC. What is recommended next. Also heard to take eggs I eat, bake the shells, crush the shells and add to food. What are your thoughts on that? The girls seem to be doing great. Had one with pasty butt but got her clean. Feathers are coming in fast. How old before I need to move them outside to the coop? How old before they begin trying to get out of the brooder I have. The sides are about 18 inches high. Do I need a bigger brooder or if they can get out of that they should be in the coop? Thanks for your answers ahead of time.
