Ok so I have 4 lav that were born on May 3. Will 2-3 week older or newly hatched chicks be ok with them? I'm new to chickens. I had 5 I got from a farmer, they're lavender orpingtons. One of them was small and slow. I found it didn't make it today. I'm devastated. Is this common? They've been on heat pad, chick starter, water. I'm so worried!!!! Any advice? I'm really hoping these make it, considering getting more chicks and hoping at least 1 is a hen so I can possibly hatch some of my own. Is it easier with a hen taking care of the chicks? Do you still leave them with her in the coop if it's chilly out? Or do you take the chicks and raise them seperate? Sorry for all the questions!!!
