I have my first 5 chickens (Isa Browns) and they are almost 6 weeks old. They are such a joy to watch. Getting chickens has been on my "bucket list" for a long time. After 40 years of marriage my husband finally agreed to letting me have 5. Anyway, I am feeding them Chick Starter Grower 20% Protein (Purina Brand). They seem to be thriving on this and growing like weeds. I am wondering if I should be feeding them "grit"? I don't know what grit is but everyone seems to be talking about it. I tried to give them some mint from my garden today but they just snubbed it. What other herbs or treats could I give them. I really want to spoil them. I have 3 grandaughters who are going to enjoy them, too. And, in fact, I think my husband is getting to like them a little! I've been putting them in a small fenced area for a few hours a day until our run is done so they do get to eat grass and bugs. I am also wondering at what age I can let them go free range for a few hours a day - while I keep my eyes on them! Will they know how to get back into their coop? I have visions of me chasing them all over the field to catch them. They were so adorable tonight. They were all sitting on their perch ready to go to bed before dark tonight.
