So I have 1 EE, and 2 GLW, all are 6 days old, GLW seem fine, but the EE is lethargic, she lays down a lot, and her crop is 2x the size of the GLW's. These are my first chicks, this could be normal for all I know, but I am a little scared. They are house in a very large cardboard box brooder, with unlimited medicated chick starter & water. Bedding is pine shavings. All 3 have had pasty butts once or twice, but I cleaned them easily, with no problems. Should I be controlling their food intake? I thought they should have as much as they want for the first 2 weeks, is this correct? Please tell me what your thoughts on this sweet little EE are. Thank you!!
