I have a batch of chicks (7 weeks old) in a brooder inside my house and am wondering about a few things...first, in the past I've always just given the chicks medicated chick starter crumbles (by Blue Seal) until the time they go into the coop with the rest of the adult hens (6 - 9 weeks usually) at which time they eat the Egg Maker crumble (also Blue Seal) from the feeder that the rest of the adult hens eat. I was told this was fine by the local farm store that I get the feed from, but just looked into it online and see that the Egg Maker crumble is recommended for 20+ week old chickens...so what's the worst that would happen if chicks around 2 months old ate it? They've done it before and I haven't noticed any problems (at least none seemingly related to feed) but if it's a big issue then I'll have to do something about it. Second, I just ran out of the medicated chick starter crumble feed; what should I give them now? The bag doesn't say anything about it, but the Blue Seal website recommends to give it to them until 8 weeks old, then switch to Grower Cal (mash) from 8 to 20 weeks. I've never used Grower Cal before and am wondering how they would respond to being switched from crumbles to mash...also, the stores that carry it are closed today (Sunday) and tomorrow (Labor Day), so that makes it difficult. The bigger box stores that are open carry Purina, so would it be alright to get Purina Start & Grow instead? And if so, should I get it medicated or non-medicated? Finally (and unrelated to feed for the most part), when can I put the chicks in with the older hens outside? I read on here that it's not recommended until they're 16 weeks old (4 months) but there's no way they could fit in the brooder up until that age. I've moved 6-9 week old chicks in there before but it's never easy, as the bigger hens will usually attack the chicks and will require a lot of supervision...plus, it gets cold this time of year (average of 65 degrees during the day, 50s at night) and I'm always concerned about the chicks being out in that temperature, although I've never had any die from it before. On the other hand, as the chicks get bigger and bigger they become cramped in the brooder inside the house and will begin flying around and attacking each other, plus it becomes much more cumbersome and messy to take care of them in the house at that age. So what should I do? Thanks for any help or advice!
