Hello all. Year 2 in this super-rainy hot summer (Florida) All my chicks this year are hatched under my own hens from their own eggs. I have some that are a few weeks to a few months old. Everyone looks perfectly healthy, active, no problems with looks or behavior. It's been very wet (they live in a large run and do not free range) and I'm seeing slightly foamy yellow poop. Last year it decimated our incubator-hatched chicks, with only a few surviving with intense nursing. I'm also remembering years of raising chickens free ranged, hatched by their own mothers, and seeing such poop, but never having anyone act sick. So I'm not sure what factors were different for the group last year. Anyway - I have Tylan 50. I'm wondering, should I proactively treat the chicks even though they look fine? Might they be ok? Is it better or necessary to treat? These are destined (all but one or a few) for freezer camp. We have our laying flock and setting hens. The older chickens mostly drink from nipple waterers, but there's a large waterer on the ground the chicks use. So I can put something in there that would mostly go to them. What should I do? I'd rather not give medicine unnecessarily. Especially since I've literally raised hundreds of them free range and naturally and never had them get sick. But our flock is so small I need to be careful too. Thanks for any suggestions!
