I have 4 young hens (about 20 weeks) I am in the final week of grow feed and them I ma going to switch them to layer feed. I am not thinking they are eating as much as they have in the past - the feeder is VERY slow to empty this past week or so. I have been giving them a cup (24 0z size) of scratch and grain with feed mixed in every other morning cuz its been cold here (ok cold for sacramento) so I know they eat that and they are eating the green easte/trimmings I bring them from work, but are they geting enough food?? Feed is in their coop, water is downstairs both a auto system with cups and a jug of H20. any thoughts??? thankn you in advance!!
