New to having chickens. We have 2 hens and 3 laying pullets(well it seems like the pullets lay every other day or so). They love it when I give them veggie and fruit scraps and weeds from the garden. How much can I give them? I've heard that chickens will only eat what they need and then stop, is that correct? They also have organic feed, which is mainly corn and soy, and oyster shells. + water with ACV. Also, wondering about feeding the hens their egg shells. I know that they should be smashed into tiny crumbles, but I ask: do the eggs need to dry out first? How often and when can I change from oyster shells to their own shells? Do chickens get diarrhea? Something i should worry about? Thanks for reading my post and for any help!
