How? I'm about to combine new younger birds with 1 yr. old birds in a new coop. I can easily separate the younger ones with chicken wire until the older ones seem to be willing to accept them. How do I keep the food separate if you aren't suppose to give laying feed until they are actually laying? Very likely the older birds are going to get to the younger birds food and vs versa. How have you guys handled this?? Thanks in advance.
