My birds are sometimes finicky like that at certain times of the year.
Usually at least once a year they decide scratch is a waste of time
and turn their noses up at it. So I usually give them a mix of
everything I have, scratch, layer pellets, sweet feed, turkey/gamebird
feed and some wild bird seed all mixed up. Depending on how much there
is to eat while free ranging and what's available for them, I'll mix
in more of one or the other kinds of feed depending what they need at
that time, or at least what I FEEL they need, lol. When free range
proteins (like bugs) and greens (grass and weeds) are sparse, I'll
even mix in some dry cat food (not a lot tho) and rabbit food
occasionally. Sometimes they do not eat much of anything that I put
out, but it is there if they want it.
