I bought the girls a Flock block from Purina as a Christmas treat for them. Needless to say, they love it! But what concerns me is that they are now no longer eating their pellets like before. I haven't filled their feeder since Christmas. I used to fill it 1-2x/week. Now granted they also have had their share of Christmas leftovers but it just seems like they aren't eating as they did before the Flock Block. They are also molting & I'm lucky to get 1 egg/day. Should I take away the Flock Block or just let them enjoy it???
