Could my 2 month old chicks be overloaded with worms?

[WillowMoonWyandottes]

Just found roundworms in my 2 year old hens poop. My birds have been going through ALOT recently first Coccidia and then Infectious Bronchitis and now worms! I have other threads, I linked them below. I’m treating my larger birds with Safeguard goat dewormer but what about my chicks under 2 months old, should I treat them also? I honestly don’t even know if they are even 1 pound yet. They are very malnourished from Coccidia (which I’ve already treated them for, for over a week) but Corid didn’t seem work for them and I ended up having 2 chicks die. They are acting a little better now but that makes me wonder since the Corid treatment wasn’t working could they have died from a worm overload? I added pictures of the 2 month old chicks poop which still has a lot of blood/tissue like material in it and is still watery even after a full treatment of Corid, they either still have coccidia or worms maybe? I’m honestly not sure what is going on at this point, there is so much happening at one time.

It's certainly possible that worms could be the problem with chicks at 5-8 weeks old since they've been on soil, and they can cause shed intestinal lining as well.
Give each chick 1/4ml Safeguard liquid goat wormer. Give it orally with a syringe without a needle. Dont add it in feed nor water. You wont know if they ate or drank enough of it to be effective, nor ate or drank it at all.

It would also help to switch them to a new run as this prevents them from picking up the parasites right back from their own old droppings.
