Feed everyone chick feed or all flock with oyster shell on the side for your layers.I bought her as a chick from tractor supply, as far as I know she should have been vaccinated. Unfortunately I can’t afford to take her to a vet. And I’ve been giving her a syringe of water with sav a chick every few hours to make sure she doesn’t get dehydrated.
Unfortunately I don’t have a way to separate my layers from my babies so even having separate feeders I can’t stop them from eating what they want. And I did have some moldy squash I threw into the compost they could have gotten into.
