About a week ago, a chick was found at my local river. He hasn't grown in the week we got him, and today we took him to a local zamzows, where the manager keeps chickens himself. We had him look at our little mystery chick, and he told us he hasn't grown because he is extremely malnourished. He used everything he got ( very little from what we saw where we found him) and put it all to keeping his inner organs going. We brought him back home, and I got started. I'm keeping him away from my other chicks, and keeping him in a hygienic area, since he is so weak, and I'm worried about hid immune system. He gets unlimited chick starter, mixed with a tiny bit of garlic, which I read is good for their immune systems, and water that had some apple cider vinegar. He's under a heat lamp 24/7 and all that. I'd there any foods that are good for putting weight on a chick? We were also told he is most likely a rooster, which may be the reason he was most likely dumped. We plan on keeping him, since we wanted a rooster, and he has the looks of an Americana chick. Any tips on how to get him up to par, feathering nicely, good weight, etc? I'll do anything to help the little guy. He is an absolute sweet heart, and just loves a good cuddle.
