Oh boy! I pray I'm ready for this. Post office said they are due to arrive approximately 1030-1100 (AM). At max chicks would be at the post office for 30 minutes, hopefully a lot sooner. [First time owner] I read that 21-22% protein is most ideal. I bought DuMor chick feed 24% & 20%. Best option I have is to mix 50/50=22% protein, right? Could not find niacin, and have also heard conflicting opinions on the use. I guess I should note I am only expecting 2 ducklings, 1 male, 1 female pekin. Plus 5 chicken chicks. They all will arrive from ideal poultry, and I purchased probiotics, and electrolytes. We also have a new kiddie pool, and a paint roller dish and rubber shelf liner for the ramp to their 'starter' pool (paint roller tray). Their carpeting will be hay, and separated by a wall of sorts, so they don't mix feeds/environments. After two to three weeks, I plan to fully introduce chicks to ducks only while free ranging until they all reach maturity. Any positive tips to help for when they arrive tomorrow would be ready appreciated. I am worried to the point of nausea about getting chicks mail order, especially since this is the first 24 hours, and although they're coming from Texas to Florida, we are still going through a cold front and I'm worried sick about them. Can anyone tell me what else I should do? Hope I've got everything covered for tomorrow, my baby's lives depend on it!
